Firmware R211 release

Hi,  Just created a the firmware update on USB flash drive and about to upgrade the firmware.  I have a problem though.  No keyboard function after booting from the USB drive with the firmware on.  Only got USB ports on my PC no PS/2 on the mobo at the back…  Tried 2 keyboards, current KB Blackwidow Ultimate and Logi G11, both don’t work on the firmware upgrade screen.

Using z77x UP5 TH mobo if that’s any help to anyone that could help me if there’s some setting in the BIOS is need to enable for keyboard funtionality on the FW upgrade screen.
