GA970A-DS3P USB 3.0 problems

[killabee]

Hi! I bought my Gigabyte GA970A-DS3P mobo about three weeks ago (also a Gigabyte r9 270x with which I'am super satisfied) and everything was working fine, until today when I powered up my computer and my keyboard and mice weren't working. They were connected to USB 3.0 ports and when i plugged them into 2.0 they started working. WHat might be the problem?

just power off (reboot is not sufficient) your system every time the via usb3 controller disappears - it's a design flaw apparently affecting all amd boards with this particular via controller - you have to live with this problem until you change board.
