What driver does it use? If your not sure you can check here to see what it uses. More than likely you will need to use the ndiswrapper module to get it working. Some say that ndiswrapper doesn't work very well but I haven't tried it. There should be some posts on ndiswrapper here and how to set it up from the posted links.
