Who were you logged in as? Your permissions on /dev/sg0 don't
allow read/write access for normal users.

Try doing

chmod o+rw /dev/sg0

(you must be root to do this) and then try again.

As well:

1. what version of SANE are you using?
2. did you get one of the updated SnapScan backends from
http://www.cs.ualberta.ca/~charter/SnapScan/snapscan.html?
