Ubuntu does not work with Samsung Galaxy phones (Unable to open raw device 0)

[Andre]

If your device is not supported please open a new bug specifying:
* device in question (make / model / release)
* output of `mtp-detect` when the device is attached
* output of `lsusb` when the device is attached

This bug will be a catch all for recent Samsung Nexus & Nexus 7, or please comment what other recent Andorid 4.x devices are affected.

Yes there is a lag in providing support for the most recent devices. As soon as the fixes are available, SRUs will follow.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Laurent Dinclaux (dreadlox)]

That isn't true that "Android 4 will not support anymore usb mass-storage protocol" it is up to device maker to provide sdcard slots or "internal sdcard". In that case mass storage will be available.

But more devices do not have sdcard support or sdcard like internal memory. So, those are only accessible using the MTP protocol which needs to be implemented in GVFS to automatically mount in .gvfs users folders.

[Sebastien Bacher (seb128)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

[Andre (ajx)]

I've created an upstream bug report: https://bugzilla.gnome.org/show_bug.cgi?id=666195

[mlaverdiere (mlaverdiere)]

I'm on Ubuntu 11.10, using a Samsung Galaxy Nexus with Android 4/ICS.

What I observe is that connecting the GN in ptp mode behaves almost exactly as it if it was connect as a USB mass storage device, i.e., automount, icon (camera) appearing in the Launcher & Nautilus, possibility to create/move/delete any kind of files/folders, etc. Even with Banshee (and Rhythmbox I presume), if you put an ".is_audio_player" at the root, the GN will me recognized as a Media/Audio player!

Anyway, I guess that if the mtp connection was providing the same kind of access as ptp (by default, GN is set to connect as mtp device), it would be easier for novice users to have their GN phone works with Ubuntu.

[mlaverdiere (mlaverdiere)]

The only problem (limit) with ptp so far is that, strangely, it appears to limit the space access to +/-1,5 GB, as there is +/- 13 GB available (free) on the phone...

[Martin Pitt (pitti)]

We'd need to add a udev rule to allow users to access these devices. I figure we don't want to collect a whole lot of vendor/product IDs, is there a way to tell that an USB device is an Android one?

Can you please run

  udevadm info --export-db > /tmp/udev-db.txt

in a terminal and attach /tmp/udev-db.txt here, with the phone connected?

[mlaverdiere (mlaverdiere)]

Here are the requested log files, one when the phone is connected in mtp mode, the other in ptp mode.

I don't think (I may be wrong) that there is a magic way to detect all Android devices, as there are so many manufacturers and products... Anyway, most Android phones will continue to rely on USB mass storage, as Android 4/ICS still support this mode when there is an SD card inserted in the phone (which is usually the case). Up to now, Galaxy Nexus is an exception, with very few others so far.

[mlaverdiere (mlaverdiere)]

Other file.

[traverlaw (david-traverlaw)]

I'm using Ubuntu 11.10, with a Samsung Galaxy Nexus with Android 4.0.2

I cannot get USB support to work with either Media Device (MTP) which gives no response at all, or Camera (PTP) which will trigger a camera icon. When clicking "open" on the icon, I get a window with a "Galaxy" title in Nautilus, follwed by a long pause, and the eventual message, "The folder contents cannot be displayed. Sorry, could not display all the contents of "Galaxy": DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

Thus, I am forced to use "Airdroid" rather than accessing the device in the normal manner.

[traverlaw (david-traverlaw)]

Here is a copy of the tmp/udev-db.txt that corresponds to my prior posting.

[Andre (ajx)]

@traverlaw Did you try to follow the tutorial at "OMG! Ubuntu" which is linked in the bug description?

[traverlaw (david-traverlaw)]

Andre asked, "@traverlaw Did you try to follow the tutorial at "OMG! Ubuntu" which is linked in the bug description?"

Yes I did try it, several times, in many different versions as found on the web, and it does not work. I also upgraded via compiling to libmtp-1.1.1 and it still did not work. File access to a Galaxy Nexus via Linux should be an easy plug-in-the-phone treat, not requiring hours of searching the web, compiling new packages, editing files, and manually mounting and unmouting. When finally able to get to the files with the new lebmtp, they could be seen, but not accessed. Picutres would not show, music would not play. It was, from the user perspective, a wild goose chase that led to nothing. Android, it appears, is leaving Linux behind, and that is a very bad thing for Linux.

[mlaverdiere (mlaverdiere)]

Once again, just to put the story straight: Android 4/ICS is ***still*** supporting USB mass storage (UMS). The only thing is that some devices (such as Galaxy Nexus) have only one partition (i.e. without SD card) and thus, can't rely on UMS since this would lockup the whole system. These devices have to rely on other widely known protocol like mtp and ptp which are usually supported under Linux for years. On this explanation, see: http://www.engadget.com/2011/11/21/ice-cream-sandwich-supports-usb-mass-storage-after-all-galaxy-n/

So basically, the only thing to resolve here IMHO, is to have the Galaxy Nexus well recognized by Ubuntu as a mtp/ptp device (and, if possible, to provide complete file access with these protocols).

[bill troop (w-troop)]

I am using Ubunto 10.04 LTS. I followed the instructions in the referenced document. However, when I execute the mtp-detect | grep idVendor or mtp-detect | grep idProduct commands I get no output. It just returns to the cursur.

[Steffan Jacobs (steffanjacobs)]

I have recently bought a Asus Transformer Prime which gives no feedback on my Kubuntu 11.10 laptop when I hook it up in MTP mode. Mass storage does not seem to be one of the options for USB though that might be because I did not have any external memory hooked up when I connected it. Using the instructions a OMG ubuntu I was able to mount the system quite quickly.

I also own a Samsung Galaxy S. Though this still has mass storage support for the built-in memory, I tried hooking it up in MTP mode for a change. Something actually did pop-up and seemed to give some access to the phone. It seems however that I did not have access to all the files as I do seem to have on Windows.

I do hope that this can be included in the next release of (K)Ubuntu because a lot of people will be running into this now. If Ubuntu truly wants to remain a distro for the not-so-technical users things like this should really be picked up early.

@w-troop: you might have to install the package mtp-tools (i.e. execute 'sudo apt-get install mtp-tools' ). Though I would still except some output even if it is not installed. You could try executing just 'mtp-detect' and see if you can find the values yourself.

[zaiger (brian-zaiger)]

I'm using Cyanogenmod 9 with my Motorola Droid *with an SD card*, and I still cannot connect via USB. Also there is no option to change to MTP in the notification drawer like OMG! Ubuntu suggests so I cannot even fix it that way ):

[mlaverdiere (mlaverdiere)]

@Zaiger:

Currently, under Cyanogenmod 9 (still in early development), USB mass storage works with some devices (http://forum.xda-developers.com/showthread.php?t=1374497), but not (or not so well) for others. It's a Cyanogenmod 9 development issue. Again, ICS is built to supports USB mass storage when the device has more than one partition. For devices that don't, we need good mtp/ptp support under Ubuntu.

[Olivier Mengué (dolmen)]

libmtp is involved in MTP support because udev rules and protocol implementation are provided by that package, so bundling a recent one is required.
There are a few open Android 4 related bugs in its bug tracker (I can't link to them in this bug's meta because LaunchPad think that the bug tracker is at LaunchPad and refuses to monitor SourceForge ones):
http://sourceforge.net/tracker/?func=detail&aid=3489472&group_id=158745&atid=809061
Some are recently fixed (January):

[Laurent Dinclaux (dreadlox)]

When pluging in an MTP device nautilus should show the device content like with any mass storage device, no matter how, this is the behavior poeple are especting.

[Javier Scappini (jscappini)]

I cannot make this to work either. I have a Galaxy S2 with ICS 4.0.3 and Precise. No luck till so far...

[Alessio Treglia (quadrispro)]

This bug should be fixed by the latest release uploaded to Precise.
Could anyone confirm that?

[Krešo Kunjas (deresh)]

it works for me now. it automounts in nautilus through gphoto2 mtp backend.

handset is samsung galaxy s2 with latest cyanogenmod 9 ( ICS 4.0.4)

[Alessio Treglia (quadrispro)]

Good! Closing for now.

[futtta (futtta)]

still on 11.10, can't test if fix works (but looking forward to this in a couple of days time)

for the record; i'm on a samsung galaxy sII with official samsung ICS ROM and although I do have a external sd-card, I don't have the option to mount it as USB mass storage, only choices are between MTP and PTP.

[Shriramana Sharma (jamadagni)]

I have a Sony Xperia Neo V which I recently upgraded to ICS and I have upgraded my Kubuntu installation to Precise. If it is true that the problem has been "fixed by the latest release uploaded to Precise" as per comment #24 please tell me from a vanilla installation what packages should I install to enable Precise to read my SD card via MTP protocol. The curious thing is that Ubuntu has always read my MP3 player (also on MTP) without my needed to install any specific packages, so I wonder why I have to install now only?

[mlaverdiere (mlaverdiere)]

@jamadagni: I don't know precisely what package is needed, but in my case, I have libmtp9, libmtp-common and libmtp-runtime installed (by default) on my Ubuntu 12.04 machine and I'm able to mount my Galaxy Nexus 4.1 ICS phone. However, when I plug the phone, nothing happens, i.e. no automount; I have to switch phone to ptp mode (or if it is already to ptp switch to mtp), to have the phone mount with one or this mode. Hope this helps.

Galaxy S2 with ICS

[Jesueldo (jesueldo)]

Galaxy Nexus with ICS 4.0.4 . Aparently, everthing works, but when I try to copy music to the phone, or it copies to root folder or gives an error

[Andre (ajx)]

Nexus-S_4G with Android 4.0.4 can be mounted as easy as it has been with 2.3.x. Vanilla Android seems to work great.

@Jesueldo: You might want to try it with a .is_audio_player file which allows to specify the location of your music files on the device when using software like Rhythmbox or Banshee: http://almost-a-technocrat.blogspot.com/2010/11/isaudioplayer.html

[Maraschin (carlo-maraschin)]

When I tried to use rhythmbox to acess a samsung table 10.1:
"Unable to open the Samsung GT-P7310/P7510/N7000/I9100/Galaxy Tab 7.7/10.1/S2/Nexus/Note device"

The same problem with Samsung Galaxy SII...

The best would be to be able to access it using Nautilus since it is not only photos and music, there are videos, ebooks and any other type of file that we may want to transfer between the devices!

[Maraschin (carlo-maraschin)]

Importance: Wishlist ?! WHY??
That is BAD! You are downgrading something that millions of user would like to integrate, linux with any android device in an EASY way! Please!

[Svein Tore (sveint)]

I cannot connect my stock Galaxy SII (ICS). Nothing happens. gMTP doesn't work either.

How can this be fixed if people are still experiencing issues?

Precise with latest updates.

[nLinked (nlinked-deactivatedaccount)]

No way is it fixed for me, Galaxy S2 with official ICS, Ubuntu 12.04 updated. Neither MTP or camera or debug modes. In MTP, it does automount in nautilus and shows the files and folders on the root of the phone, but all folders say 0 items inside them, and going into any folder shows no files or folders inside (when I know there are).

Uploading a file to the root or inside a folder shows as if its transferring, completes, but doesn't actually go on the phone's storage.

[Ingo Reimann (ubuntu-i-reimann)]

Same is true for me: Galaxy SIII, Ubuntu 12.04. When i plug in the phone, two nautilus windows (vie gphoto2) open for the internal and the external sd-card. In MTP mode i get the content and even may read files from the external sd, but only in the root-folder. Aall other folders i may browse, but they appear empty.

I may also create a file, that somehow may be changed on the card. When i plug of and on, the file can`t be read anymore, just be deleted.

[Andrew Cowie (afcowie)]

I have a Samsung Galaxy Tab 10.1 and despite a fully up to date Precise system, MTP support is not working.

USB connection attempt to a Galaxy Tab 7 plus.
I'm trying to connect a Galaxy Tab 7 plus to my PC (lubuntu 12.04). The usb connection works not so perfectly: lubuntu gives
this strange message: "Error initializing camera: -60: Could not lock the device"

and asks if I prefer to open the device (a portable audio player ) with vlc or open in file manager. Obviously I open file manager and I can see the sd card directories but they are empty . If I try to copy files, it's not allowed.

I get the same mtp-detect output as acunningham on Samsung Galaxy S3, Ubuntu 12.04.

I followed the instructions in the howto in the bug description above. When I attempt to access the mounted directory, it hangs a long time then reports:

  ls: cannot access /mnt/android: Transport endpoint is not connected

/var/log/syslog shows these messages:

  kernel: [ 5647.472020] usb 2-1.1: reset high-speed USB device number 5 using ehci_hcd

S3's are selling like hotcakes and Ubuntu is increasingly popular. It would be super to have them work together.

[Siep Kroonenberg (siepo)]

Also same output as acunningham with Samsung Galaxy Tab 2 7.0,or P3110.

[Robin Sheat (eythian)]

Fix is most definitely _not_ released. When I open a nautilus window from the galaxy nexus in MTP mode, it spends a long time thinking and then pops up an empty window. Is someone able to change the status back to "confirmed"?

[Onlyodin (ubuntu-xsnet)]

I have installed all updates for 12.04 (including libmtp* and mtp-tools) and the issue is not fixed for me also.

Attempting to browse the device when in MTP mode results in a delay of 2-3 minutes followed by an error the same as the DBus error described in comment #10.

[Andreas Hasenack (ahasenack)]

When it says "Fix Released" like that, without the name of an Ubuntu Release, then it means it's fixed in the development release, which is Quantal.

Are you running Quantal? If the fix is indeed there, and confirmed working, then this bug here needs to get a SRU to try to get it into Precise and the others, if applicable.

[Robin Sheat (eythian)]

Comment #24 says:
> This bug should be fixed by the latest release uploaded to Precise.
> Could anyone confirm that?

And the "Fix Released" status was set on that basis.

I'm confirming that this is not the case, it is not fixed in the latest releaase uploaded to Precise.

[Andreas Hasenack (ahasenack)]

I can't change the status either, and I doubt people are looking at this bug anymore because it's "Fix Released".

I think a new bug is in order, pointing back at this one, or maybe marking this one as a duplicate of the new one. Specially because there is no "precise" task here anymore, since the bug was opened during the precise cycle.

[Robin Sheat (eythian)]

We could use bug 972311 if it can be unmarked as a dupe of this.

[Justin Clark (jerico74)]

FWIW, I can't get my Galaxy S3 connecting properly under 12.04. I followed the steps in OMG hot-to, but I get the "-60" error when I plug the phone in (before I even get to the "android-connect" step).

[Alessio Treglia (quadrispro)]

Targeted to Precise right now, I'll work on it as soon as possible.
In the meanwhile could anyone try to reproduce this bug with the version of libmtp currently available for Quantal?

[Alistair Cunningham (acunningham)]

Not sure if it's the correct version, but I downloaded this file:

http://archive.ubuntu.com/ubuntu/pool/main/libm/libmtp/libmtp9_1.1.3-24-g9aca343-3ubuntu1_i386.deb

mostly guessing, but I wonder if this time taken is longer than any reasonable timeout and is causing things to fail. My phone has been used for some time now, so is full of junk. I seem to remember having it work once or twice when I first got it, so perhaps something in libmtp is going through and indexing _everything_, which takes too long.

"time mtp-files" takes a similar length of time, so this seems plausible to me.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Siep Kroonenberg (siepo)]

I noticed that the only person who claimed that it worked (#25) had CyanogenMod installed. I just installed CyanogenMod on my Galaxy Tab 2 7.0 too and now suddenly it works for me too, via mtpfs.

I remember reading somewhere about Microsoft's mtp stack with DRM and the standard mtp stack without.

[Christoph Langner (chrissss)]

@Siep Kroonenberg: Did you wipe you device while switching to CyanogenMod? Remeber, MTP works well, as long as your Smartphone contains just a couplfe of files. As soon as you transfer your whole music collection to your phone, MTP breaks on Ubuntu.

[nLinked (nlinked-deactivatedaccount)]

I believe CM7 will work but not CM9 (ICS).

[Dave Thomas (davet)]

CM7 on a Galaxy Nexus or other ICS device? Not going to happen and also nothing you would want to do.

Simply put, MTP on Ubuntu is broken unless you have very little on your internal storage. If you wipe it and have few files it wont time out, but once you actually start using the phone and files build up it will fail. This is easily confirmed.

[Siep Kroonenberg (siepo)]

@Christoph Langner: I wiped the device but not the sd card while installing CM9 on my ICS machine. I keep my data mostly on the sd card.

For me, MTP did not work at all with the Samsung firmware, at least with mtpfs and adb: mtpfs would mount but not give a directory listing, and 'adb devices' came up empty except once. With CM9, I can get an directory listing and give adb shell commands.

I never use mtp as mtp and haven't tested big file copying actions.

[Onlyodin (ubuntu-xsnet)]

Alessio Treglia asked in post #53 if this could be reproduced in Quantal...

I've run up a Quantal VM in Virtualbox, connected the phone through to the VM, it's detected and suffers the same issue as I get from Precise, which is the same as the error in post #10:

"
Sorry, could not display all the contents of "Galaxy Nexus": DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply.
"

[Siep Kroonenberg (siepo)]

I did some more testing with my GT2/CM9:

From GT2 to pc:
copying a directory with a few largish files went ok

From pc to GT2:
copying a directory tree to the GT2 resulted in the directory tree being created but individual files ending up in the root of the SD card.
copying an 125MB file to the GT2 went ok.
copying a 2.5GB tv recording to the GT2 resulted in a corrupt copy.

If I manage to run mtp-detect within three secs after plugin, I get the following message (see attached file), but still unity / nautilus will only the top level folders on the internal phone and the sd card, but they are all empty.

[Andrea Amoroso (heiko81)]

I got a Motorola Xoom 2 (European edition with HoneyComb 3.2) and with Ubuntu 12.04, it doesn't automount automatically. I just managed to upload files on it using GMTP, but it's kind of buggy. After I launch GMTP and open Nautilus, it shows me the new device, but, if I click on its icon, I always have a system error. I think that this should be solved asap, because many Android devices are being upgraded to ICS and JB.

[Siep Kroonenberg (siepo)]

Copying files with adb works well for me, with a standalone adb from http://code.google.com/p/texasice-cream-sandwich-mirror/downloads/detail?name=adb_fastboot.zip&can=2&q= . No need to unmount the sd card on the tablet.

With the original ROM, nothing worked for me. With CM9, at least adb is fine. mtp only sort-of works.

Mtp may be ok for media, at least if it works, but I much prefer proper access to the filesystem, which adb provides. When googling for adbfs I get several hits. I think something like that would be just what I need.

[Mark Dwyer (mdwy62)]

I have ICS with stock ROM on GSII (Sprint: Epic 4g Touch) with 12.04 LTS. When I plug the phone in I get the 2 nonsearchable top folders described above (see #38)

gphoto2://[usb:002,022]/store_00010001
gphoto2://[usb:002,022]/store_00020002

Followed the omgubuntu directions referred to above, android-connect command does not work. mtp-detect returns:
VID = 04e8
PID = 6860

After a few minutes a volume icon shows up on the desktop, but trying to open it yields the error:
Error: Error when getting information for file '/media/GSII': Transport endpoint is not connected.

gmtp fails as well.

I have an external SD card in my phone, but I do not have a USB option under Settings>Wireless and Network > More.

Phone Dialer: *#7284# has a USB option, should be set to USB/PDA This does not seem to help either. Tried switching and resetting back to no avail.

Debug mode is on.

[hoover (uwe-schuerkamp)]

I can confirm this problem exists on Cyanogen Mod 9 on my new S3 / i9300 (flashed with the current cm stable version).

When I plug the phone into 12.04 desktop (32bits), I get the error message "can not exclusively reserve device" (from memory), USB debug mode is "on".

[Jan Gutter (ubuntu-jangutter)]

Hi,

Have you tried using jmtpfs?

http://research.jacquette.com/jmtpfs-exchanging-files-between-android-devices-and-linux/

It's working for me on my Galaxy Nexus (JB and ICS), and I've also had luck with it with a Galaxy S3 (ICS). (I'm using 12.04 with the latest libmtp)

Unfortunately mtp is still really slow: keep in mind it was never really designed to scale, and mapping it on to a filesystem will always be imperfect.

[hoover (uwe-schuerkamp)]

Thanks for pointing out jmtpfs, it seems to work ok on Linux Mint 10 using a current libmtp version. speed isn't great (5MB/sec), but I can live with that for now until the ubuntu folks get their act together!

[Andreas Hasenack (ahasenack)]

I updated my galaxy nexus to jelly bean (4.1.1) and the problem remains.

[EverydayInventors, LLC. (bst7b5apmx)]

The Nexus 7 also does not emulate a mass storage device, only MTP and PTP are supported. Using Ubuntu 12.04 I can only access a subset of the Nexus 7's directory hierarchy related to the camera when using PTP. Currently, setting up fuse to allow access to MTP devices is not particularly intuitive but once set up correctly, MTP does seem to allow access to what appears to be the full directory structure of the device.

[Martin Stjernholm (msub)]

People (like me) who believe they're still affected by this bug, and hence don't agree with its "Fix Released" status, may want to weigh in on bug 986722 instead.

[psypher (psypher246)]

This bug is not fixed. My Nexus was working 100% in Nautilus up until the last update I did a couple of days ago and now all get it this error when connecting it:

Sorry, could not display all the contents of "Galaxy Nexus": DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

[Bernard Decock (decockbernard)]

Same problems when accessing an Archos 101G9-tablet

1. Command mtp-detect takes about 2 minutes in order to complete (output is ok : see attached file)

2. gmtp fails most of the time and once it crashes, it keeps on crashing

3. Browsing the file-systeem is very slow (minutes) although downloading files is very fast!

[nLinked (nlinked-deactivatedaccount)]

I have just installed Cyanogenmod 9.1.0 stable on my S2 and after connecting my phone by USB to Ubuntu 12.04, and then popping down the top menu on the phone and selecting USB storage mode (or similar), I have full access to everything on the device as normal.

For me at least, this problem is sorted!

[Bklyn (v-launchpad-bklyn)]

@nLinked (#87): have you experienced this bug before and now things work? Does your phone have a significant number of files on it on it (perhaps you wiped as part of your upgrade)?

It seems unlikely this bug has been fixed given that no releases have been made that reference it.

[Jeremy Nickurak (nickurak)]

nLinked's comment is largely irrelevant to this defect, he just turned on
USB mass storage mode on his phone. Not all phones support it, and it has
all sorts of negative side effects (even if you can do it, it means the
phone can't access anything on that storage, potentially including
applications).

[nLinked (nlinked-deactivatedaccount)]

Sorry, you are right, what works for me in CM9.1.0 is in fact mass storage mode. Glad to see it back for now, but it does of course dismount the storage from the phone while in use. So the MTP problem is still there.

[hoover (uwe-schuerkamp)]

So CM 9.1 brings back usb mass storage mode, hopefully on the S3 too? I wouldn't mind not being able to use the phone while it's connected as usb mass storage.

[Onlyodin (ubuntu-xsnet)]

As far as I'm aware, USB Mass Storage is still available in 4.0/4.1 (Vendor Optional), but only for external storage (MicroSD storage). For those of us with Internal storage USB Mass Storage is not an option.

It may also be possible with CM9 if they partition the Internal Storage to give the appearance of both Internal and External Storage - but it remains that only the 'external' storage is usable with USB Mass Storage.

[karthikjain (karthikjain)]

Recently upgraded my Galaxy Nexus to 4.1.1 JB and now i'l facing problems with MTP.

PTP works fine but MTP works occationally.
Nautilus detects the Filesystem as gphoto2, In the properties i'm able to view the used space and unused space correctly, but the folder contains nothing.

[Juan C Nuno (juancnuno)]

@karthikjain Which version of Ubuntu are you using? I haven't been able to get even PTP working on Precise.

[Anthony Borrow (arborrow)]

Just tested MTP with 12.10 and a Galaxy Nexus and still seeing the "Sorry, could not display all the contents of "Galaxy Nexus": Timeout was reached". Peace - Anthony

I have been working on native mtp support in gvfs. The details of that work can be tracked in the linked upstream bug. This will allow Nautilus to correctly access android devices - it won't help with any of the other applications, as they have to be rewritten to avoid this bug.

[Dimitri John Ledkov (xnox)]

gmtp is using libmtp, such that if it is fixed there gmtp will start to magically work.

[Dimitri John Ledkov (xnox)]

udev has nothing to do with this bug. The rules for actual devices are provided by libmtp package in the file 69-libmtp.rules

[Dimitri John Ledkov (xnox)]

The libmtp status fix released is bogus, as libmtp does not use launchpad for bug tracking, they use source forge and there is no bug link.

[Laurent Dinclaux (dreadlox)]

If libmtp is effectively fixed, when will the fixed package be available in Precise?

It's actually not clear that the gmtp bug is invalid.

gmtp uses a particular set of libmtp API calls that aren't functionally compatible with Android 4.x devices. libmtp has a separate set of calls that are compatible (these are what go-mtpfs and my gvfs mtp backend use). So, gmtp would need to be updated to use these different set of calls before it will ever work, unless the libmtp authors decide to reimplement the broken calls in terms of the working ones, which is theoretically possible, but, I think, unlikely.

Back to precise, libmtp-* is 1.1.3-1.
I wonder is it a bug introduced in 1.1.4-1?

[Vitor Lamas Gatti (vitorgatti)]

The bug is still present in Ubuntu 12.10... is this a bug with libmtp or with Ubuntu? Does this work on other distros?

Its working with Kubuntu 12.10 with 3.5.0-17-lowlatency #18-Ubuntu SMP

go-mtpfs works excellently for me by manually mounting. It seems to implement the mtp spec properly. Surely it wouldn't be difficult to just use that for mtp mounting rather than libmtp?

Thanks for the effort!

[Mio (m10)]

but i can move files from the phone to the computer and back :) thx!

[Philip Langdale (langdalepl)]

Mio,

USB3: There are still compatibility issues with usb2 devices plugged into usb3 depending on the physical controller and kernel used. So I'm not surprised to hear there are problems. This is low level and not related to mtp.

Copying folders: Yes, this doesn't work, due to how Nautilus handles the operation. It should internally transform it into mkdir and individual file copies, but it does not, and it's not possible for a gvfs backend to sanely emulate this behaviour. I should change it to fail the operation, rather than make an empty directory. It's on my list.

Moving files: This is an optional feature in the MTP spec and no device supports it - the only thing you can do is move to PC and back again. Yes, it's ridiculous, but there you go.

Thanks for the feedback!

[Mio (m10)]

USB3, copying files: should I file a bug to linux/nautilus?

Moving files: couldn't it automatically move the file/folder to /tmp/ and then back to the new location? or must this be better done in nautilus too (file bug?)?

Thank _you_ for your work!

[Philip Langdale (langdalepl)]

Mio,

USB3 would be a kernel bug. You should look for unhappy messages in dmesg output.

Moving files: There are two answers to this one. It is physically possible to implement a "fake" file move in the backend, although if that's the path you want to go down it should be done in gvfs core code and not in each backend (the ptp backend has this fake move logic in it, but no one else can use it). But the most robust implementation would be in nautilus, because then it would understand what's really going on and could keep track of the file as it moves around the system and minimize the chance of data loss. It would also be able to give feedback to the user that two copy operations are taking place.

[H.-Dirk Schmitt (dirk-computer42)]

Problem is not resolved with the most current libmtp 1.1.5 (see http://sourceforge.net/projects/libmtp/files/libmtp/)

[Philip Langdale (langdalepl)]

Dirk, As discussed above, mtpfs will never work with an Android 4.x device due to how it uses libmtp. No updates to libmtp will ever change that.

As for your mtp-detect error, that's likely due to another application already talking MTP to the device (eg: if you'd attempted to mount with mtpfs, or if gvfs ptp was trying to communicate with it - which will happen automatically if you have a default Unity desktop, or if gvfs mtp is communicating with it, if you're using my version of gvfs). The MTP protocol only supports one application communicating with the device at a time, so if another one tries to do connection initialization, the device gets confused and can respond in fairly unpredictable ways.

[Marius Groeger (marius-groeger)]

Philip, thanks for all your work on this. With your PPA nautilus sees my i9300 allright but upon mounting it I only managed once to actually see any contents. In all other cases there was no visual error and the device appeared mounted, but there was just no content and I could not create anything as well.

Is there any way to debug this?

I also noticed that even though your solution is using gvfs, it is limited to nautilus, ie. other gvfs aware file managers such as thunar can't be used. I know this is exactly as announced by yoursefl, but our of curiosity: is this something to be fixable on your end or is it a limitation on those other file managers part?

[Laurent Dinclaux (dreadlox)]

2 working workaround solutions:

- jmtpfs: http://research.jacquette.com/jmtpfs-exchanging-files-between-android-devices-and-linux/
- go-mtpfs: http://www.webupd8.org/2012/12/how-to-mount-android-40-ubuntu-go-mtpfs.html

[Philip Langdale (langdalepl)]

Marius,

Are you making sure the phone is unlocked when you plug it in? If the phone is locked, then you'll see an empty nautilus window. Once you unlock it, press F5 to refresh the window (My quantal builds are against libmtp 1.1.4 which has no event notification support - if built and run against 1.1.5, it will auto refresh when you unlock), and you should see some content.

As for Thunar, I'm slightly surprised it doesn't work. I haven't tried it so I have no idea what it does but my work should be transparent to anything that uses gvfs 'normally'. It's possible that Thunar handles some of the backend registration differently from Nautilus and may need explicit code changes to know that the mtp backend is available.

[Dan Näsman (dan-naesman)]

There are ONE POINT THREE million devices activated each day that are not "plug and play" with Ubuntu!

I have been frustrated with the lack of Android 4+ (MTP) plug and play for some time and I have tried gmtp and go-mtpfs but none have been stable. I handle my family's 7 android devices and the proposed workarounds works now and then for some of the devices. Last time that I needed to offload 9 GB of pictures from a Galaxy SII phone I had to revert to a virtual Windows 7:(

I propose to make MTP "Plug & Play" in Ubuntu, current LTS and future releases.

[Artyom (artyom-szasa)]

I've been watching the thread for a while now as I still can't find a solution to get any files to/from my mobile devices (HTC One X and Acer A500) but by using ssh (either installing ssd on mobile devices or connection to my laptop/desktop). Both my laptop and desktop are running Ubuntu, usually the last stable one, so now it is Quantal.

First of all I would like to thank the ones working on the solution to this problem as it is a shame that Ubuntu does not support the andriod devices out of box (I've tried to use them since Oneiric with no success).

I've tried the gcfs-mtp solution mentioned above almost with out success. It allowed me to browse folders and open PDF files (only !) on my devices, but I could neither copy or move any files nor open image files.

Now I've udated to the newer version and got even worse results: I still can open a pdf in the root folder of my HTC, but when I try to enter the DCIM folder nautilus closes with "Connection closed" error (I see a localized message in hungarian but if it is important I can check the message the original message). Also I've got
 pool[26210] general protection ip:7f95b802a69c sp:7f95aeffcc28 error:0 in libgobject-2.0.so.0.3400.1[7f95b7ff9000+4d000]
error in my kern.log.

When using my Acer A500 the same thing happens if I try to open the root folder of the device...

Can I do anything to help solving these problems? SHould I post any logs or try anything?

[Norbert (asterix52)]

> but when I try to enter the DCIM folder nautilus closes with "Connection closed" error

I got this message often with the old version of gvfs and libmtp. Have done a restart after updating?

[frotz (frotz)]

I'm using a Galaxy Tab2 7.0 and have had similar problems. I cannot access the device at all using any of the known mtp tools (mtpfs, go-mtpfs, or jmptfs). I supposed that maybe upgrading to libmtp-1.1.5 will help.

I downloaded the libmtp-1.1.5 tarball, dropped in the debian/ directory from the previous version's deb src, changed debian/changelog and built a new deb containing the various packages for version 1.1.5.

mtp-detect succeeds. go-mtpfs and jmptfs work. Sometimes "fusermount -u foobar" will fail because the system thinks I'm still doing something in foobar. Regular mtpfs works unacceptably. It seems that it does a union mount of the internal sdcard on top of the external sdcard and sets all the permissions to 777.

I hope this helps.

I would really suggest to get these packages to Natty-backports since the amount of Android devices using MTP in this world is enormous.

My gut feeling is "Raring onwards", as it's quite an intrusive change
which by far doesn't meet the usual SRU criteria.

Dave,

Unfortunately, these newer Motorola devices appear as... wait for it... a CDROM drive.

The CD image contains the installer for some windows software that they want you to run, which will send a magic USB packet to the phone to switch it into MTP mode. That's really what's going on. I haven't found any useful information about this online, so it doesn't appear anyone's reverse engineered the magic packet. Sad sad sad.

That's quite common indeed; there is usb-modeswitch to get devices
from this useless fake CD-ROM to "real" UMS/MTP mode, so perhaps
usb-modeswitch-data needs to be updated for your model? It might help
to file a bug against usb-modeswitch-data, anyway.

I encounter this bug also with my Intel Orange phone with Android 4.0 and Ubuntu 12.04
(Device 0 (VID=8087 and PID=09fc))

This is a very BIG regression, because it used to work normaly (at fast speed) on my computer since last week where I have let ubuntu proceed to updates.

[tlue (tlueber)]

connecting and browsing with nautilus is fine with my HTC. Copy Camera-Pictures to Linux works fine too.
But now copied files onto that phone from a WinXP and when wanting to copy those files towards Linux I get the error:

"Error getting file: -6: Not Supported"

The file size is 368MB

output of mtp-detect:

libmtp version: 1.1.3

actually it now works for me when adding this ppa:

sudo add-apt-repository ppa:langdalepl/gvfs-mtp
sudo apt-get update

apply all updates and restart computer. found the info here: http://www.webupd8.org/2013/01/upgrade-to-gvfs-with-mtp-support-in.html

With Ringtail-13.04 I can access Android 4.2.2 data on my Galaxy Nexus .
Does not show up like a USB device on my desktop but File Manager shows it
and can mount/unmount and copy data to it.
A big advantage for 13.04 over 12.10. Thanks to all the folks who made this work again.

[Oren Held (oren-held)]

I've been too lazy to try go-mtpfs, up until now.
It just works flawlessly with Galaxy Nexus / Android 4.2.2, unlike libmtp and its ecosystem (gmtp, rhythmbox, nautilus).

[Derek Simkowiak (ubuntu-cool-st)]

There was recently a change to the adb tool. It now does authentication; the user is prompted to "allow" a new computer when the phone is connected to it. The old adb is not compatible.

This change is probably why it fails, even though MTP on the Samsung Galaxy Nexus previously worked.

I used the new adb (with the authentication) to manually push files. That worked fine. Trying the other forum posts (like changing the udev rules) did not work for me.

It was very aggravating to get the cool new phone (Nexus 4) and then not be able to transfer files to it.
