dronus, thank you for reporting this and helping make Ubuntu better.
To see if this is already resolved in Ubuntu, could you please test
http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?
** Description changed:
If I scan a page using the Agfa SnapScan 1212u, the scanner bar does not
return to the edge but stops in the middle of the scanner at which point
the scanner powers off.
If one now tries to do another scan, the motor give a squeeking sound
for some seconds without movement, and the software reports a connection
failure.
If the scanner USB connection is un- and replugged, the slit returns to
it's home position and it works again.. for one scan.
Some time ago, the scanner worked fine. I don't know how long this is
ago.
+
+ WORKAROUND: Manually disable scanner USB autosuspend by executing as root:
+ echo -1 >/sys/bus/usb/devices/USB_ADDRESS_OF_SCANNER/power/autosuspend
