IIRC- there was a bug in Ubuntu's SCSI scanner udev rules, which Olaf reported to them? The general idea is to add a line to a file in /etc/udev/rules.d, which will set the permissions on the scanner to something more 'permissive' :) I think you might get more help with that specific problem on an ubuntu forum, as perms tend to be distro- specific.
