Connecting pixhawk to windows 8

I just got a new windows 8 computer and I cant get it to connect to my pixhawk in APM planner. When I plug in the pixhawk to the computer it does not recognize it. If I go to my devises it sees the PX4FMU but it says driver not installed. How do I get it to work? Thanks

had the same. just replace the USB cable (faulty) and it will (probably) be recognized
