[quote=84206]Hey untakatapuntaka! I currently use the old model B with a 1200 mA (1.2 A) power supply, and got everything working without problems. I have a usb dongle for a keyboard and the 360 receiver connected, no extra hubs whatsoever.

If you get the 360 controller, be sure to buy the “for Windows” one (comes with receiver) or get the regular one and a PC receiver in ebay (I’d stick with the first option, you’d end paying the same and you’d get an official receiver). Also, if you don’t have a batteries charger, you’d want to buy the “play & charge” kit (10 bucks, helps you loading the batteries while playing).

Thank you very much for the response =)
Just got a couple of wired 360 controllers from a friend and I’m gonna try them asap =)
