[sane-devel] Canoscan FB1200S

[m. allan noah]

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.
