There's only this one list, so that's the place to ask questions.

That's only one part of the story. You also need to load the 'scanner' 
module. Since it won't recognize your scanner by default, you have to supply 
the vendor and product ID:

modprobe scanner vendor=0x04a5 product=0x207e

You can also set those options in /etc/modules.conf, e.g.
"options scanner vendor=0x04a5 product=0x207e"
so you dont't have to load scanner manually.

Look in /var/log/messages for the output, it should recognize your scanner.

That's o.k.

No you don't need to, and you shouldn't.

Just /dev/usb/scanner0 is enough. Delete the 'usb' at the beginning (which is 
the cause why sane can't find your scanner).

You may have to upload a firmware file to the scanner before you can use it 
in sane. Look at http://snapscan.sourceforge.net for details.
