BT voyager 1010 and Knoppix 4

Hi,

I am a complete noob to knoppix but really want to use it. I am trying to find drivers for the BT voyager 1010 modem or the Airstation G54 keychain adapter. I have tried taking the drivers out of the windows system folder and using ndiswrapper to install it. The file i used is RT2500USB.SYS, I installed it successfully but when i list the installed drivers it says 'invalid driver'

I have no idea why, i it to do with it being a .sys rather than a .inf ??

where can I get working drivers from?

thankx
