I have recently bought a new Gigabyte GA-X79S-UP5 motherboard a couple of months ago. I am running Windows 7 on it which is working with 4gb of ram. When I connect any device in the USB 2.0 port then it works properly but if I try to connect any device in the USB 3.0 then it will not work at all. When I went in Device Manager then it was showing me unknown device under them. Can anyone tell me how do I get the USB 3.0 to work again on this motherboard? Thanks.
