Good. Installing XSane should do no harm, though.

I guess you already found the documentation on http://snapscan.sourceforge.net
- it should point you in the right direction.

You have to specify the vendor and product ID while loading the scanner. Try
"modprobe scanner vendor=0x04a5 product=0x20de". Then run "cat
/proc/bus/usb/devices" and check that you see "Driver=usbscanner" in the
entry for the scanner. Then try "scanimage -L" again.

There's nothing you can configure for the controller. You only have to make
sure that an appropriate driver module ("uhci" or "usb-uhci") is loaded.
> Should I use dev/ttyUSB0 or /dev/usb/scanner0 ?? Does it matter?
Yes - You should use /dev/usb/scanner0. I guess /dev/ttyUSB0 won't work (but
it never crossed my mind to try it).
