Hmm.  It might be useful to post the output of
  'sane-find-scanner', and
  'sudo sane-find-scanner'(or however you want to run the command as root)

What are the 'default' permissions and group (assigned by udev) on your
scanner device?

Perhaps you could try unplugging the scanner and confirming that the
appropriate device file is being removed/created by udev.  If udev is
indeed handling the device, then the application of the rules file
(/etc/udev/rules.d/025_libsane.rules on my box) is either borked (reinstall
libsane and/or udev), or there are multiple rules matching your scanner
(and the last one is screwing up the permissions set by libsane.rules).
