"Could not claim the IO device": Canon IXUS 65, Edgy

[Mary Gardiner]

When I attach my Canon IXUS 65 to my computer via USB, Import Photos reports "Could not claim the IO device".

Importing photos from this camera worked on Dapper.

[Gerhard Rauniak (gerhard-rauniak)]

I have the same Problem with Edgy and my IXUS 65:

tail -f /var/log/messages:

if I start gnome-volume-manager-gthumb %h I get:

This is normally a bug in some application using the D-Bus library.
libhal.c 995 : Couldn't allocate D-BUS message
error: libhal_device_get_property_type: (null): (null)

and when the window to import the fotos pops up I get this error message:

An error occurred in the io-library ('Could not claim the USB device'): Could not claim interface 0 (Operation not permitted). Make sure no other program or kernel module (such as sdc2xx, stv680, spca50x) is using the device and you have read/write access to the device

[Mary Gardiner (puzzlement)]

Moving to confirmed.

For others, one fix is to add a line that reads
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="30fe", MODE="0660", GROUP="plugdev"
to /etc/udev/rules.d/45-libgphoto2.rules (and restart udev) -- I am not sure whether that is the correct fix or not.

[Gerhard Rauniak (gerhard-rauniak)]

That fixed my problem with the Ixus 65.

I´m really impressed about your "response time". Only 6h to solve my problem. That´s great. Thank you very much :-) :-)

[Brian Elliott Finley (finley)]

This also fixed the issue with my Casio EX-S600. It's USB id is:

  ID 07cf:1043 Casio Computer Co., Ltd

So, by adding this line:
  SYSFS{idVendor}=="07cf", SYSFS{idProduct}=="1043", MODE="0660", GROUP="plugdev"

to my "/etc/udev/rules.d/45-libgphoto2.rules" file, and doing an "/etc/init.d/udev restart", camera auto-discovery, and photo/video removal capability started working again. :-)

[justplayin (paddyschwartz)]

I get the same messages as gerhard rauniak in comment 1 under edgy and with the camera "Ricoh Caplio G4 Wide". The auto-import under Dapper worked fine.

Adding the new line to "/etc/udev/rules.d/45-libgphoto2.rules" as described above didn't work for me. I saw that an entry with the correct values for idVendor and idProduct already existed in "/etc/udev/rules.d/45-libgphoto2.rules".

lsusb gives me:

With tail -f /var/log/messages I get:

By typing "id" in the console I get:

So I seem to be member of the plugdev group.

When trying to list the photos on the camera with "gphoto2 -L" I get:

patrick@pat:~$ gphoto2 -L

Following the advice in the output of gphoto2 I did a debug with

and attached the output in a file to this comment.

I'm trying to compile libgphoto2 from the svn to see if this changes anything.

[justplayin (paddyschwartz)]

I compiled libgphoto2 but wasn't smart enough to get gthumb compiled with photo-import enabled because it didn't recognise libgphoto2 I had compiled from svn and installed with checkinstall.

I reinstalled libgphoto2 and gthumb from the official repos and found that in digikam and gtkam the photo-import worked right away. So I'll be using these programs for the import of photos.

I don't understand anything about libgphoto2. So I might be on the wrong track here. But when I plug the camera in and the command "gnome-volume-manager-gthumb %h" gets executed gthumb looks in the directory /usr/lib/libgphoto2/2.2.1 for a camera driver. In the directory I can see two drivers for my Ricoh camera:

ricoh.so
ricoh_g3.so

When I run the program "/usr/lib/libgphoto2/print-camera-list human-readable" it says that the driver for the "Caplio G4" is "ricoh_g3.so" listed. Strange that gthumb doesn't find it or can't use it.

[Marcin Niechcial (bastard79)]

i have a similar problem with my Canon A610
in dapper autodetect - autorun gnome-volume-manager-gtumb works fine, but after upgrade to edgy it stop auto working.

after plug my camera to usb nothing happend :( but when i'm typing manualy in conosole gnome-volume-manager-gthumb, then i can import images as well as in dapper.

> i have a similar problem with my Canon A610

you might wanna file a new bug report for that

[dailyglen (dailyglen)]

I have the exact same problem for a Fuji Finepix F30, to fix I did:

1) $ lsusb | grep Fuji
Bus 002 Device 006: ID 04cb:019b Fuji Photo Film Co., Ltd

2) Added to the file: /etc/udev/rules.d/45-libgphoto2.rules
SYSFS{idVendor}=="04cb", SYSFS{idProduct}=="019b", MODE="0660", GROUP="plugdev"

3) Turned off camera

4) Restart udev: /etc/init.d/udev restart

5) Turned on camera, and voila

Do you want us to open a separate bug report for each incident or should we change the title of this one to be more generic?

I would think it is easier to keep track of these via new bug reports. but of course, it's up to Martin Pitt.

Had the same issue with a Kodak EasyShare C643. The fix explained by dailyglen worked for me.

i'm tested my camera at company computers on clean edgy install & dist-upgarded from dapper and there is everithings OK with no problem with my camera :( only in my home PC it stops work autorun.

maybe some packages are missing ??
a have no popup when camera is found in system, then i can ignore this or import images, if import then run gnome-volume-manager-gthumb
How can i run this popup manually ?

sorry for my english, i'm still learning ;)

[Ryan Lovett (ryan-spacecoaster)]

I had to the same thing with my Canon A630.

SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="313a", MODE="0660", GROUP="plugdev"

Wouldn't it be easier to just glob all the idProducts?

[Mika Wahlroos (mpw)]

I experienced the same problem with a Nikon CoolPix L2. Setting the permissions in the udev configuration solved it. The id of the devices is as follows:

ID 04b0:0148 Nikon Corp.

The camera worked fine on Dapper. I guess there's a particular reason why the default permissions were changed (or so I assume before further research) but it seems to cause some problems. This shouldn't really happen since people who aren't very savvy at searching for solutions to such issues are left in the cold.

[Sirius (vorstar)]

I've just had the same problem with my Nikon P4 in PTP mode, and the same fix worked out.

It looks like this bug is pretty common, so I advice changing the bug title to something like: "My USB camera doesn't work, 'Could not claim the IO device'", and getting everyone using Edgy to know about it.

Anyway, thanks for the hint.

Maybe adding more device definitions to this udev rules per default would be a good idea. Merging Dapper and Edgy files maybe, as it worked just fine back in Dapper days.

Thanks.

Hey, just to let you guys know, if you happen to own an HP Photosmart E327, add this line to your /etc/udev/rules.d/45-libgphoto2.rules :

SYSFS{idVendor}=="03f0", SYSFS{idProduct}=="8b02", MODE="0660", GROUP="plugdev"

And to anyone else that is having this problem - simply type "lsusb" in the terminal after your camera is plugged in and turned on, search for the line from the lsusb output that identifies your camera, and add a new line to the 45-libgphoto2.rules file and replace the idVendor 4 set of characters with the first set of 4 from the lsusb line, and then do the same for idProduct for the last 4 (after the colon).

[Mikko Saarinen (mikk0)]

My Canon PowerShot A75 worked fine until I started toying with usb bluetooth dongle - don't know if that is the reason, but now all I get is this message (An error occurred in the io-library...) :(

mikko@mini:~$ lsusb
Bus 001 Device 008: ID 04a9:30b5 Canon, Inc. PowerShot A75

mikko@mini:~$ cat /etc/udev/rules.d/45-libgphoto2.rules | grep 04a9 | grep 30b5
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="30b5", MODE="0660", GROUP="plugdev"

So the line already exists in udev rules.
I can get the photos from the camera if I start the program with command:
mikko@mini:~$ sudo gnome-volume-manager-gthumb

Why does this require sudo? My id tells that I'm in the group plugdev:
mikko@mini:~$ id

The good thing is, that at least I can get the photos by using sudo, but I have no clue why this doesn't work as a regular user anymore :(

This is just a guess, and is probably not the issue. But perhaps you ran it
as root at one point, and it created files in your homedir (or a subdirectory
thereof) that belong to root (and you're now not able to change them)..

If you no files in your homedir that should belong to any other user than
yourself, do:

sudo chown -R :plugdev <homedir>

..replacing <homedir> with the path to your home directory, such as:

sudo chown -R :plugdev /home/mikko

The bug you are experiencing, though, is a separate bug from the one this
bugreport is for, and any further correspondence on it should go in a
separate bugreport.

My Notes on How I Was Able to Make My Camera Connect on Edgy

Getting Canon S400 Elph to Connect

FROM........
https://launchpad.net/ubuntu/+source/libgphoto2/+bug/67532..............

- Following aldegaz's instructions above, and changing the 3rd line in /etc/udev/rules.d/45-libgphoto2.rules to:

SUBSYSTEM!="usb_device", GOTO="libgphoto2_rules_end"

[my comment]
--- this appears to work so far a/o 3/27/2007 17:06
 f-spot works, and that's all I really cared about anyway.

NOTES:

the line (3rd line) that got replaced is this.....

 BUS!="usb*", GOTO="libgphoto2_rules_end"

It seems to be important that this information be on the 3rd line of file. I tried other stuff, adding lines etc. and left other lines commented out that forced this line away from line 3. That caused the restart of udev to fail!!! I've never seen an application be dependent on the actual line number of something, but it really, really seems to be important to gphoto2 or udev in general.....very strange but must be remembered!!!! KEEP THIS IN MIND!!!

Also, BE SURE TO BACK THIS FILE UP BEFORE YOU MESS WITH IT!!!!!!!!!!! I nearly got in trouble, because my changes and commented-out lines caused udev to fail. Fortunately, I had another box running Edgy to fall back on and see how it's stuff looked. LESSON LEARNED!!!....don't screw with stuff w/o backing it up first!!! Enuf said.

I get the same error message reported in the first post to this bug when starting gnome-volume-manager-gthumb on feisty:

The message reported by the dialog is different though. It says "PTP Protocol error, data expected"

I tried adding the product id to libphoto.rules, but this doesn't fix the problem for me.

The camera is a Casio EX-Z750 (07cf:103b) and worked fine with Dapper. It stopped working some time during an Edgy update, and is still broken in Feisty.

Hi Bros!
I am working with Aiptek mini Pencam 1.3, Vendor ID 04fc; Product ID: 504a. Then i did the fix for both bug 64146 and bug 91250
add a line: SYSFS{idVendor}=="04fc", SYSFS{idProduct}=="504a", MODE="0660", GROUP="plugdev"
and
changing the BUS!="usb*"... line to SUBSYSTEM!="usb_device"...

But nothing can help! I still got the following error when trying to
access the camera to get info or download picture (by gphoto 2):

 gphoto2 --camera "Aiptek Pencam" --port "usb:001,016" --list-files

*** Error ***
An error occurred in the io-library ('Could not claim the USB device'): Could not claim interface 0 (Device or resource busy). Make sure no other program or kernel module (such as sdc2xx, stv680, spca50x) is using the device and you have read/write access to the device.
*** Error (-53: 'Could not claim the USB device') ***
