Add your user id to the floppy, audio, video, cdrom and plugdev groups. If you do this manually (as root), you can edit /etc/group and append your user id to each of those preceded by a comma; e.g.,
Code:
...
plugdev:x:83:root,your_user_id
...
You can also use the
usermod utility to do so.
Log out and log back in.
