I haven't connected an android device with my PC via USB since a
long time. As I needed to get some log data I've tried it again and
to my surprise I could access the internal memory (At the time I've
got my Galaxy Nexus this didn't work on Linux due to a bug). After
several updates of the Android SDK I've got my log data and wanted
to copy some data on the phone. It didn't work. First I've got this
error message:
Unable to open MTP Device '[usb:003,004]'
After a second attempt I've got than this:
Error: no such interface ‘org.gtk.vfs.Mount’ on object at path
/org/gtk/vfs/mount/1
On another PC with the same Ubuntu version it still worked. First
I've thought that the update of the Android SDK were at fault. While
looking around the system for changes I've got over this entry at
the output of dmesg:
[12781.532868] usb 3-2: usbfs: process 8267 (banshee) did not
claim interface 0 before use
So I've turned out Banshee Media Player and connected the phone
again. Now I could access the internal memory again. This behavior
is even reproducible. Every time I listen to music I can't access
the internal memory but as soon as I turn off banshee I get access.
