Read through the forums but my lack of knowledge with Linux is preventing me from making this work.

I bought a DWL122 (USB, supposed to be Prism 2.5 compatible)
But have been unsuccessful getting this to work.
Tried a clean install of Knoppmyth, but no network card found.
Dropped to a prompt, and did modprobe prism2_usb, and it succeeds (registered the driver)
Plugging in the device I get vend/prod 0x2001/0x3700 is not claimed by any active driver
iwconfig gives 'no wireless extensions'

What else do I need to do?

Thanks for dealing with a Noob
