This udev rule is for SCSI scanners, so it probably is not going to

This is probably not going to work, because /dev/scanner* and
/dev/usb/scanner* permissions are controlled by console.perms. So
they will be set to mode 600 and owner root is no-one is logged in
at the console, and to the console owner if there is. But if you are
not getting the scanner symlink, then the problem is probably that
it is not covered by rules in 60-libsane.rules
It would probably help to see any log messages generated when you
plug in the scanner.
