Airport Extreme Base Station and USB DSL Modem

Hi

I have a Powerbook G4, an Airport Extreme Base Station and a Speedtouch USB 330 ADSL Modem.

How do I get the Modem to connect to the Base Station? The modem only appears to have a USB cable coming out of it, and a phone connection. The Base Station has a USB port which is supposedly for printers?

Is there some kind of converter or cable I can use to connect the two?

Confused....

Hi there and welcome, I found this online.

It sounds as if you just connect it to your phone line, and then just connect it to your computer via the USB port. It also sounds as if you may need a install cd. Looks as though you might be out of luck using the airport.! Maybe you could talk to your dsl provider about getting a different type of modem one that has a ethernet connection!
