saned requires write access scanner USB bus for its process and to usblp/bind in order to rebind multifunctional printers back to usblp (for printing with p910nd). A hotplug script monitor new USB devices for scanners. Scanners are detected by searching /usr/share/sane/<vendor>-<backend>.usbid for the device product_id. The package saned creates user saned:scanners. Access is granted to group scanners. The default xinetd conf was updated to run as saned:scanner. sane-daemon pkg now has a postinst trigger that runs udevtrigger for granting perms where there are connected scanners during installation. Existing hotplug scripts from hplip were removed. They were mostly useless. Signed-off-by: Luiz Angelo Daros de Luca <luizluca@gmail.com>
