Is your normal user a member of the "scanner" group?  What are the
permissions on the scanner devices.  ('ls -l /dev/scanner*')

I have one system where the hotplug stuff seems to struggle at getting
the permissions right.  If the scanner is connected when the computer is
turned on then the permissions don't get set and only root can scan.  If
you then unplug the scanner's usb lead, wait a few seconds and then plug
it in again the permissions do get set and anyone in the scanner group
can scan.

(Well, when I say, "one system" - it's the only system which I have with
a scanner.  I don't know how widespread the problem is.  Plain Sarge
installation.)
