Re: gigabyte ga-990fxa-ud3 usb ports not working
Have a similar Gigabyte board and have had no problems with it. You should go into the BIOS settings and see what is there that will allow you to enable Legacy USB support. You will probably need to turn that on.
Also, if these are USB 3.0 ports, you are going to have major problems. Legacy mode may allow them to work in USB 2.0 mode, which should then work for you.
Ubuntu 16.10 Mate, Mint 18 Mate; MS Win 8.1, MS Win10 Pro.
Will not respond to PM requests for support -- use the forums.
