With the help of a different keyboard, go into your BIOS and look for a function that disabled USB devices during bootup.

Hello
I'm sorry to hear that. Obviously there is an incompatibility with this mainboard.
It could only be solved by the manufacturer of the motherboard I'm afraid. Sorry that I cannot help you further in this specific case.
