Hello. I am a user of knoppix 3.3. I have installed it some days ago. But when I try to write a CD I can't. I can mount the CD but when I run the k3b it says there's no cd device, this as common user. But if I was root the k3b find the cd device and I can write, clean cd, etc....

That is a problem security of my system? Or I ought to make modifications in my system?. How I can make that my cd-r works?
(It's a LG).


Thanks.
