Communications Controller

I have a PCI Simple Communications Controller that Win 7 says I am missing the driver. I have two external drives plugged into the PCI USB 3.1 that came with the MB and they are not showing up. That lead me to believe it is the USB 3.1 that is the problem. I downloaded the latest driver from ASUS site. When I installed it said I already had the driver. So, I selected repair. It is not working still. I tried using Device Manager and browse to driver, nothing.
Does anyone know the problem is?
Thanks.
