I don't think anything was changed concerning this between 1.0.3 and
1.0.6 but the change of sanei_scsi_find_devices() for devfs. I don't
know much about devfs so I'm mostly guessing here.

Doesn't the configuration file /etc/devfs/perms help? See man
sane-scsi for details. Depending on the backend and it's configuration
file, the scanner may be contacted via "/dev/sg?" or (if devfs is
enabled) the devfs SCSI file. If the permissions of the latter are
correct, it shouldn't matter, how the device is accessed.

Could you provide more information on what you think is wrong with
SANE in this field? Currently I don't see the problem, because it's
not the job of SANE to set the correct permissions.

Bye,
