Scanner Access Enabler

[ Thanks to jhansonxi for this link. ]

"There is a problem with scanner device permissions on Ubuntu. Regular users (UID>999) can access libsane applications like Xsane and Simple Scan without problems. Linux Scanner Server, which is running in Apache as www-data, can't access them without a chmod o+rw on each scanner device. Nobody seems to know how the permissions work so this has to be fixed manually in a terminal. This is not n00b friendly so I created a GUI application that automatically changes the permissions of every scanner device.

"The application relies on scanimage and sane-find-scanner utilities to identify scanner device ports then simply does a chmod against all of them. It supports USB, SCSI, and optionally parallel port (-p parameter) scanners and has been tested against the same ones I used for my LSS patch. It uses the same universal dialog code as webcam-server-dialog so it should work with almost any desktop environment."
