mtp filesystem can't mount

[Typhoe]

Hi,

I tried to connect my phone (Samsung GT-I9300 / Galaxy S3 on CyanogenMod 9.1) to my notebook.

Quantal doesn't seem to be able to mount the 2 filesystems availble on the phone (internal storage and external one, microSD).

In Nautilus, the mount points appear and disappear every few seconds.

I don'tget this behaviour on an other Quantal PC, so maybe it's due to the USB3 available on this notebook (the other PC is USB2 only, and on it, I can connect my phone).

Regards.

In syslog, these lines are repeted again and again:

Hi all
I fount this post where and seems that 1,1.5 version fix the issue (1.1.5 is in 13.04)
http://sourceforge.net/mailarchive/forum.php?set=custom&viewmonth=&viewday=&forum_name=libmtp-discuss&style=nested&max_rows=100&submit=Change+View

I compiled from source and installed in 12.10 libmpt1-1.5 and now I can mount my Galaxy S2 storage (so I can copy files) but I still have problems with Openshot and Rhythmbox.
I think that I should try with 13.04 and see if it works fine

Ciao
Giovanni

Hi
I have the same problem here with Galaxy S2 (I9100) on Ubuntu 13.04.
Using Cyanogenmod 9.1 (android 4.0.4) with kernel 3.0.32-CM

Nautilus shows up the android device, but i can't mount it.

$ mtp-detect
Error: Unable to open ~/.mtpz-data for reading.

with 1.1.6 (in 13.10) and with USB-debug ON (on android -> settings -> developer ), it seems to solve at least the errors as per post #2

[poikiloid (efelthauser)]

I have this problem in Kubuntu 14.4's Dolphin and Konqueror file browsers, even with USB-debugging on.
