I'm looking for a wireless game controller for my HTPC. Can anyone provide me with some feedback? I tried to use a USB extension cable for my current controller, the Gravis Gamepad Pro (USB)...but it won't recognize my controller with the USB extension cable attached... Note: I can't figure this out for the life of me - it works on all other computers - but not the one I want to use it on....why does this always happen to me Any feedback on a good wireless controller would be much appreciated! Thanks!
