So I used a plug n play cable to connect one of my 360 controllers to my laptop via usb. I have the microsoft xbox 360 accessory software installed and updated, when i plugged in the controller it installed the device drivers without incident but the software nor the controller are indicating that it is connected, when i press the home key it just flashes the 4 leds and nothing else. The game isnt picking it up either. What am i missing?

I am running 64bit vista and yes I got the correct software (for 64bit vista) directly from the ms website.
