It is an old hat, but no solution has yet been posted.

The question:

How does one get the Binatone ADSL 500 USB modem to work under Knoppix 4.0?

The idea: work the external USB modem in the same way as it does under winxp.

The PC recognizes as much of the modem :

from usbview:

class 255, vendor ID 0x509 (Aztech systems), product ID 0x80f vers. 0.01
Maufacturer 68396021

found on Bus 001, dev 002, ID 0509:080f Aztechsystems

I tried:
adslconfig -> asks me for stuff regarding an ethernet card, that I do not (yet) have.

What is missing? What needs doing to have the Internet singing and dancing with
this kit and Knoppix 4.0?

Best Regards,
Bernd.
