I am running Windows XP x64 at home and looking for a wifi USB adapter that would have drives for this it. I searched google over and over and couldn’t find anything that supports 64-bit windows. There are some old posts suggesting that this could work, but no, I didn’t have any luck so far. It’s strange that this is the case. I’d expect the new 64-bit technology to be more widely accepted and supported by now… but then again… do you remember when 32-bit windows came out?
