Problem solved!? Unplugged scanner and proceeded to download the latest sane* packages from
a fedora 3 mirror( and dependencies!)
rpm -Uvh <downloaded packages>
Plugged scanner back in and /dev/scanner-usb-\
roc\:bus\:usb\:001\:005 was created.
Put the right permissions on /dev/scanner-usb-\
roc\:bus\:usb\:001\:005
and it works fine for all users.
