Occasionally, I will try to play a game with my controller (X360) but I get no response. I have done a DxDiag and found the K/M, my X360 controller and then a random "phantom" controller, with a a weird Controller ID. I've got nothing plugged into my PC other than the Xbox pad, mouse and my keyboard. There are no drivers for this imaginary controller and i've fixed it before by deleting the xnacc.sys driver and Adobe Air (for some reason). They are gone so I dont know why the ghost controller has reappeared...help anyone?
