I've Just purchased a T10 iGB iRiver. And after following all the instructions on this thread and on the gphoto2 FAQ I've got everything almost working.
The problem I'm running into I've yet to find anything on. Essentially whenever I try to transfer more than 512M to the T10 it stops responding.
*** Error ***
PTP Protocol error, response expected
*** Error ***
PTP Protocol error, data expected
*** Error (-1: 'Unspecified error') ***
from then on I cannot upload anymore using gphoto2. Trying "ghpoto2 -l" yeilds:
*** Error ***
PTP Protocol error, response expected
There is one folder in folder '/':
- store_00010001
There are no folders in folder '/store_00010001'.
Even though the iRiver browser clearly shows everything I've uploaded until then. Reconnecting the T10 does nothing, the only way to get it to communicate with gphoto2 again is to delete files. At this point I might as well have bought a 512MB player.
I'm running Fedora Core 4 with kernel 2.6.14-1.1637_FC4smp I've installed gphoto2-2.1.99-3.
FWIW: Running detail debug on a sucessful transfer, and the same transfer when it fails only reveals the following difference:
