I have tried Knoppix, which I am running now ; it seems very user friendly, and it has a more customizable GUI than windows, which i like. I am very very new to this different OS business (i have just started straying away from windows), and I can't view the contents of any USB drives like my mp3 player and my flash drives. I'm assuming there is an easy way to do this, but I just can't figure it out.

I found some USB viewing program, and it shows devices like the mp3 player, so I know they're being recognised.
