Comment (by pulkomandy):
After a try to increase the timeout, I still got the bug. Further
investigagion at BeGeistert showed that the problem is actually elsewhere.
The SCSI Sync (0x35) command hangs this device. We notice it and won't use
it again after the first try, but it's too late, the device is hanged and
won't answer to anything else after that. Seems we need a quirk to reset
the device or something.
Listusb for that device :
{{{
10d6:1101 /dev/bus/usb/4/0 "" "USB MASS STORAGE CLASS " ver. 0100
}}}
This device is an "s1mp3" MP3 player. It uses a fairly widespread chip
(AK1025). I expect any device from the same vendor (10d6, Actions Ltd), to
have the same problem.
