Hi,
you probably ran into an incompatibility between the kernel and libieee.
See http://home.scarlet.be/eddy_de_greef/Sane/ for more information
(Reported problems - first bullet).
You can try to update libieee to version 0.2.11. If that is not an
option, you can try to work around the bug by creating a file called
/etc/ieee1284.conf containing this single line:
disallow method ppdev
That line should enable you to scan as root.
Best regards,
Eddy
