I have a brand new Gigabyte GA-78LMT-USB3 mobo that I installed and I can't get the USB 3.0 on the back to work. All my other USB ports work fine, but these won't work. I am running Windows 7. I know Windows 7 doesn't have a built in driver for USB 3.0 and that it can be mixed up in a bunch of different drivers and the chipset. I have installed the chipset and all drivers pertaining to usb. When I plug into the usb 3.0 in the back I can see that power is being provided but nothing happens. When I go to Device Manager it says that the USB Controller driver is missing. I have tried installing it but it says it can't be installed. I have also checked BIOS to make sure USB 3.0 is enabled and it is. On the mobo there is a f_usb30 port that I don't have anything plugged into. THere was nothing I had from my previous computer to plug in. I am assuming it is for adding additional usb 3.0 ports. I am not sure. Thanks in advance.

Solution
Hey there, your thread looked striking similar to my thread from about a year back. I had the same issue, with a different motherboard (MSI Z97 Gaming 7). Long story short, I was able to resolve my issue by entering my BIOS. I had a USB tab, inside of which was an option called "XCHI Hand-off [Enable]". I [Disabled] that, and after restarting to the desktop, I opened device manager and saw the USB controller I was missing, and all of my rear ports were functional again. Maybe this solution would work for you, good luck!
