Comment 85 for bug 25966

They didn't work (btw: official scanner drivers stopped working after 1 restart) and your package doesn't work too :/
I even turned off apparmor, but it didn't help.
Cups' logs show that everything is fine:

I've restarted apparmor and the only suspicious log line was:
Feb 21 10:18:55 localhost kernel: [ 2823.928000] audit(1203585534.741:5): type=1503 operation="inode_permission" requested_mask="a" denied_mask="a" name="/dev/tty" pid=9276 profile="/usr/sbin/cupsd"

What can I do?
