Okay so I have Vista Ultimate 64 and my xbox 360 controller. everything says it should load right up as soon as i plug it in, but it's not and i'm starting to get frustrated with it. I've downloaded and installed (running as admin) the xbox controller software and still the guide light is just flashing, my system does not recognize the device but it chimes when i unplug it and plug it back in. in the device manager it's showing up, but in control panel it does not. can anyone help me please!?!
