I'm completely new to this, so please bear with me..

i've got a compaq evo n610c with multiport wlan device (essentially this is just usb).
In windows, I'm running it with the drivers for the D-link DWL-122 usb dongle.
I've read that this dongle is working under BackTrack, however my module doesn't work.
I think I just have to add the hardware ID from the device to some file, but I have no idea where / how to do this.
when switched on, lsusb gives me:
Bus 2 Device 2: ID 049f:0033 Compaq Computer Corp. 801.11b Adapter [orinoco]

but ifconfig doesn't show the adapter...

Can soneone please help me out here? I know it shouldn't be difficult...
