Что-то у меня не работает xsane и scanimage :
# sane-find-scanner
...
found USB scanner (vendor=0x04b8 [EPSON], product=0x0133 [EPSON Scanner]) at libusb:001:008
# scanimage -L
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).
сканер точно работающий, потому что под Windows все само запустилось и заработало с софтом с прилагаемого диска.
