I have a X99 Gaming G1 WiFi with BIOS vF8c.
I plugged in my CH Products Pro Pedals, Throttle Quadrant, and Flight Yoke. They are recognized and work fine.
Just like you guys, as soon as you reboot it hangs up at the Gigabyte logo or hangs up at the Windows 7 Ultimate 64 loading screen.
I did not have this problem with a X79 G1.Assassin 2.
Aren't these motherboards advertised as GAMING motherboards yet you can't use your GAMING input devices?
Come on Gigabyte, FIX THIS PLEASE!
