[Bug 614657] New: libghoto steals and locks access to my MTP device
http://bugzilla.novell.com/show_bug.cgi?id=614657 http://bugzilla.novell.com/show_bug.cgi?id=614657#c0 Summary: libghoto steals and locks access to my MTP device Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Hotplug AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: amcgovern@novell.com QAContact: qa@suse.de Found By: --- Blocker: --- When I plug in my Creative Zen MP3 player it is automounted by libgphoto. This locks access to the device and prevents me from properly managing the music to it with banshee. The only way for banshee to be able to open the device is if I: 0) Install the libmtp package which contains all the helpful tools like "mtp-detect" 1) Plug the device in 2) When prompted about what i should do, choose "unmount" 3) Immediately run "mtp-detect" which will end up doing a reset of the usb bus. When this finishes, libgphoto will have been forcibly removed from holding the lock on the device. 4) Now start up banshee and everything will work. This is a fairly big issue as it prevents all MTP devices from working. In a way, libgphoto is correct to mount my device, but it breaks normal usage of my device completely. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Is there anything I can do to begin to get a resolution on this bug? It'd be a huge shame to ship 11.3 with this rather serious functionality regression for music devices considering this prevents normal usage. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

What Creative do you have? I see pon banshee-1 console output that if banshee is started from nautilus it also says "Received defvice command: action = Activate, device = = /home/tux/.gvfs/ghoto2-Medium on usb%3A002,002 (from DBUS I guess) ... so in that case you could umount the gvfs mount. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I figured out this trick a while ago when I couldn't figure out wtf was going wrong with my device and banshee. I assumed the mtp-detect was necessary as unmounting the device in nautilus did not remove the 'syncing' display that creative devices show when they are hooked up. This is still quite an issue because banshee can no longer support hotplugged MTP devices. Can the rule for gphoto be reduced so that it only automounts PTP devices? All devices could be displayed in natilus but if we just refrained from auto-mounting them, instead relying on the user to click on the device to mount, it would save a lot of trouble for media players like banshee. Do you have any better solutions? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

What banshee does is call Volume.Unmount () on any mtp devices. This should be the equivalent of clicking 'Unmount' in nautilus or whatever. Banshee then tries to connect to the device using the libmtp library Sometimes this works, sometimes not. The log file attached shows debug spew from failed attempts to connect to the device. Banshee makes 5 attempts separated by 2 seconds each, though it doesn't appear to matter how long is between each attempt. How can this be worked around other than banshee recommending you disable gvfs-gphoto if you have an MTP device? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
