Ahhh, ooops. Okay, permissions restored. For some reason udev does NOT create /dev/parport0 on my machine. I tried two new ways to get it to work. #1 modprobe ppdev This creates /dev/parport0, but scanimage -L still can't find the scanner. It also can no longer find the scanner when run as root! I can hear the scanner buzz for a split second, but then I get the classic "No scanners were indentified" message. #2 mknod /dev/parport0 c 99 0 -m 666 (just for testing) Exactly the same results as above. Neither root nor user can find the scanner. Scanner does a quick buzz. What do I do to get this to work as normal user?
