Hi,
GA-Z87X-UD5H Bios ver. F7 have 6 USB 3 ports on back panel and FOUR on bottom and TWO on top, right next to ps/2.
Bottom four usb 3 are not working. I tried Tried different USB 2 and 3 drives in both Windows 7 and 10.8.4. Still no luck. But, two on top and usb 3 headers are working fine. My case is Corsair 400R.
I had the exact same problem before on same board, so I got a replacement few days ago. Once I got it, it was working, but not now.
What I can try to fix it?
