Ok, this took a little bit longer time than I expected to sort out, but for those of you either with a Hackingtosh without Windows on it, or for those of you with a motherboard with a pair of NEC/Renesas USB 3.0 uPD720200 host controllers, this will help you update the host controller firmware to the currently latest known version. This may, or may not, fix some issues that you're having with USB 3.0.
Download the file below, put it on a Dos bootable USB stick (can't help you on how to make one on a Mac, I doubt it's even possible, but this is a requirement) and boot from the USB stick by pressing F12 on Gigabyte boards at boot and then select hard drives and the USB stick.
Once you've booted up you type: D200FW36 /srom 0 /writeall update.mem cfg.ini and hit enter. On Gigabyte boards you can change /srom 0 to /srom 2, but /srom 0 is an auto detect and will work on boards using different flash memory from Gigabyte. This will upgrade any and all NEC/Renesas USB 3.0 host controllers in your system to firmware version 3028 which is currently the most recent one available.
Hope this helps for those that have been having problems.
