I did find out that the keyboard has to be plugged into the keybot usb port for all features to work. Does your motherboard have the keybot usb port? Oh and it must be a asus motherboard, I guess that goes without saying though.
Rampage VI Apex does not have a USB port for keybot. The only special port is Bios Flashback (one of the USB2 ports). I just searched the Manual in PDF for "keybot", it gives zero returns.
