Hey everyone. I have the GA-Z77X-UP4 TH motherboard. Last night, the USB 3.0 ports that I had my keyboard and mouse plugged into were working fine. This morning, they weren't. I plugged them into two different ports and they worked fine. I have come to discover that only two of the six USB 3.0 ports on my motherboard are working. Two of them were working and are no longer. The other two I cannot say. Has anyone had this before? Thanks.
Update your USB 3.0 and chipset drivers for your motherboard. If that doesn't work contact gigabyte and explain your problem. Hopefully its under warranty. Could have been from a bad batch. (Gigabyte is a good brand.) Good luck.
