Wifi Adapter Driver For Osx

I purchased an old Mac Pro to use as a home server. It has no WiFi card. I have a generic Wireless N USB dongle. I got it a long time ago and it's not branded. Windows installs the drivers automatically so I never put much thought into it. System report in OSX tells me the below.

It's not showing as a network in the Network settings. Edit: I found the driver disk and it has drivers up to 10.6. Also I found a post which seems to say that it has worked on Lion. Copied below.
