I just got an Xbox 360 controller with the adapter to use it on your PC as well. I havent hooked it up yet, but I will try and let you know how it works. Thanks microsoft.
Hmm..I don't think the 360 controller needs an adapter. The Xbox one does need 1 to be able to use it on the PC though. I plug in my 360 controller with the standard USB thing it has and it works fine.
