[sane-devel] Problem with AGFA Snapscan 1212U-2

[Linus Lotz]

Hello,
I have problems setting up my Snapscan 1212U-2 with sane. I extracted
the firmware file from the CD and put it to
"/usr/share/sane/snapscan/1212U2.bin".
In /etc/sane.d/snapscan.conf I set the firmware setting as follows:
firmware /usr/share/sane/snapscan/1212U2.bin

When I try to scan I get an "Error during device I/O". Scanning for the
scanner with "scanimage -L" only works the first time, I have to unplug
it for it to be found again. The LED also changes from blinking to
steady light during the first scanner detection.

This is the debug output for two runs of "scanimage -L":
 # SANE_DEBUG_SNAPSCAN=255 scanimage -L
[sanei_debug] Setting debug level of snapscan to 255.

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

What could be the problem?
