I'm seeing the same behavior on a freshly updated 14.04
mark@ender:~$ mtp-detect
Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.6
Listing raw device(s)
Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
Device 1 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
Found 2 device(s):
Samsung: Galaxy models (MTP) (04e8:6860) @ bus 2, dev 11
Samsung: Galaxy models (MTP) (04e8:6860) @ bus 2, dev 10
Attempting to connect device(s)
At this point it hangs and you have to use ^C to get the terminal prompt back.
These two devices worked perfectly fine with Mint15 on the same hardware just a few hours before.
Using sudo does not change things so it does not appear to be a permissions issue.
mtp-detect -d generates this kind of output adnauseum
