Comment 7 for bug 75753

A "me too" here as far as the wrong group "floppy" for /dev/scd0 goes. I realised this because I added another user and since my laptop doesn't have a floppy drive I did not put it in the group floppy. When I want to play a audio-cd with sound-juicer it doesn't work and complains about "Permission denied".

udev is 103-ubuntu13.

Temporaly fixed (until you reboot) with:
sudo chgrp cdrom /dev/scd0
