I am using 12.10 Gnome Remix, and I am using a ICS device which has no option for mass storage. Instead it's a MTP device (Galaxy Reverb). I can view some of the files on my SD card from a file manager in Ubuntu. When I try to connect to the device via terminal I get the following output:

mtpfs -o allow_other /media/MOUNTPOINT
Listing raw device(s)
Device 0 (VID=04e8 and PID=6860) is a Samsung GT P7310/P7510/N7000/I9070/I9100/I9300 Galaxy Tab 7.7/10.1/S2/S3/Nexus/Note/Y.

Attempting to connect device
PTP_ERROR_IO: failed to open session, trying again after resetting USB interface
LIBMTP libusb: Attempt to reset device
LIBMTP PANIC: failed to open session on second attempt

Any ideas? I may have botched my MTP in Ubuntu altogether. I get no devices in gmtp either.
