I updated my Gigabyte P55A-UD4P rev. 1.0 BIOS from F6 to F10 using Q-Flash. I sucessfully got to the point where I think the BIOS was updated. However I can longer use my USB wireless keyboard to exit Q-Flash and restart my computer. I tried unplugging and replugging the USB receiver with no luck. Any help you could offer would be appreciated.
My assumption, been there, is that you moved the USB receiver from one USB port to another. The solution is to use another Keyboard and open the Device Manager and 'Delete' Wireless KB/Mouse then either restart or scan for new devices. The driver gets corrupted when it's moved. On my MS Wireless 6000 I've numbered the ports and used tape to label the USB wires.
