I noticed that there is a USB 3 Intel  driver (3.0.0.16) 5/13/14 listed on the Gigabyte download. I downloaded that, but it will not install saying my system doesn't meet the minimum requirements.  My device manager shows  Intel series 8/C220 EHCI 1; no specific usb 3 listed...I'm getting confused. Can anyone clarify this please?  Thanks.
