It somehow doesn't find your configuration file (snapscan.conf) at the place 
where it's looking for it (or maybe the permissions are not set correctly). 
If you compiled sane yourself the configuration file should be placed in 
/usr/local/etc/sane.d/snapscan.conf. Did you run "make install"?

There's another caveat: If the current directory contains a file named 
snapscan.conf then this file is read instead of the one in /usr/local... make 
sure you don't have an old copy of the file lying around.

The configuration file looks o.k.

No, it's done automatically by the backend.

scanimage will simply dump the image data to the console if you don't pipe it 
to a file (e.g. scanimage>test.pnm). See the manpage.

On my system I have
-rwxr-xr-x    root     root       scanimage
crw-rw----    root     scanner    /dev/usb/scanner0

All users that are allowed to access the scanner are in the group "scanner".
