Hi tcash2001. have you installed the motherboard drivers for Windows 7 64bit? You will need these for the device to be recognized; may also need to do windows updates as well.
If you could post your PC specs ( CPU, Motherboard, Ram, Gpu ) these will help us when trying to trouble shoot your problem.
Also, what device, if any, is not working?
Update thread with information and we will be better able to help you
