The exact Model I use is the F5D7050 - http://www.belkin.com/iwcatproductpa...duct_id=179211

Which according to what I have been able to find out uses the Chipset: Ralink 2570

From the backtrack site http://backtrack.offensive-security....elkin_F5D7050B it appears it can be used with backtrack as well.
