as of the 2.6.* kernels, you no longer can use the 'scanner' module, the
2.4.* versions do. You need to make sure that you have libusb installed
this will be the connection method your scanner uses. After libusb is
installed and working, if the scanner module is loaded, you will have to
unload it. Then your scanner should connect fine.
You should be able to run a sane-find-scanner and the output will show
your scanner device something like "found usb scanner (vendor=<hexvalue>),
product=<hexvalue>) at libusb:003:003" or something similar. If you are
having trouble, you need to know what backend your scanner uses with sane
and you may have to edit that <backendname>.conf file appropriatly,
pointing it to the "libusb:00?:00?" value you got from sane-find-scanner.
Then if running "scanimage -L" returns your scanner you should be in
business.
Sometimes at this point the only problem you run into is the scanner does
not work as regular user, and only as root. This is obviously a
permission issue.
