Gnomad2 gives the following error message: No jukeboxes found on USB bus The problem seems to be that gphoto2 apparently tries to mount/access the creative device. When I unmerge media-libs/libgphoto2, mtp-detect immediately sees my creative zen vplus. Reproducible: Always
I reinstalled libgphoto2 and after a reboot the problem reappeared: $ mtp-detect libmtp version: 0.3.7 Listing raw device(s) Found 1 device(s): Creative: ZEN V Plus (041e:4152) @ bus 0, dev 9 Attempting to connect device(s) usb_claim_interface(): Device or resource busy LIBMTP PANIC: Unable to initialize device Unable to open raw device 0 OK.
Assigning to media-libs/libmtp maintainers.
I don't see how gphoto2 greedily mounting the player first over libmtp is a bug.
Hmm, this might be https://bugzilla.gnome.org/show_bug.cgi?id=586778, which suggests it's a gphoto/gvfs problem and not directly libmtp.
umm, old bug, try gnomad-2.9.6 which switched from HAL to udev
