udev is a linux-only device manager thing. it is only used by sane to set permissions on devices so that non-root users can scan. therefore, all users that have difficulty scanning should try as root user first. if root cannot scan, permissions (and hence, udev) are likely NOT the problem. i see no evidence that this backend supports this scanner, other than similarity of name to other, supported models. It might require only a minor tweak to a config file, or it might take a completely new backend, depending on how similar it is to existing models. allan -- "The truth is an offense, but not a sin"
