USB ADSL modem doesn't work

[tomasko]

I am really :D happy to have discovered knoppix, I really wanted to start using Linux in some way and this is so quick and simple... anyway, I can't get my USB modem to work, when I try to configure it the wizard only detects my ethernet network card, the USB is not detected at the start either so I dunno what to do since I know very little about Linux.
Thanks in advance!!!!!
