That's the correct one, I guess. There are some other scanner drivers
for specific (e.g. SCSI-over-USB) scanners. But I guess you can ignore
those.

Ok, here it is:

Not detected by the scanner driver...

Looks ok.

Because the scanner driver doesn't know your scanner yet. Ther is no
USB scanner calss so the driver must be told every vendor/product id
that is a scanner. Either in source code or by modprobe options.
