I got this today and I cannot figure out how to get it to work with the Lego games that I have (LOTR, Star Wars, etc.). I can get into the games and the game recognizes the USB controller, but I can't do simple things like select "move up" to work on the gamepad. The gamepad is not recognized in my Finder anywhere, if that matters. http://www.ebay.com/itm/USB-Gamepad...t=Video_Games_Accessories&hash=item19c21031d6 Do I need a driver? If so, is there a good free one available? Thank you!
