The keyboard, both passthrough and onscreen are not working during the boot phase or bios screen of my Asus P5Q-EMD0 motherboard.
This is an older motherboard, I am guessing it is some USB mode incompatibility.
Other USB keyboards do work, though. And the keyboard will work once the OS is loaded.
Tried both firmware 1.1 and 1.3.1
you can try disable virtual media in WEBUI , see if it did any help .
If it doesn't work , maybe bios just not support USB composite device

Thanks for the tip! Unfortunately did not change behavior
Maybe bios lacks support for composite device as you said. However, a physical keyboard that has a built in trackpad on 1 usb is able to work. Not sure if that is a composite device, but since it is a keyboard and mouse sharing a single USB maybe it is?
Some older computers do not allow a USB drive and a mouse to be present in the same USB device. Generally speaking, it is more common for a keyboard and mouse to be in the same device.However, they may all be referred to as USB composite devices.
I experienced the same behavior on a Beckhoff C6915-0010 industrial PC. Turns out the fix was to set the USB Operation Mode in BIOS to Full/Low Speed instead of High Speed.
I documented my findings in this post:
Maybe this will apply to your problem as well.
