I recently purchased a mechanical keyboard by ThermalTake (Meka G1). After a few days, I started getting the "Keyboard Failure" during the boot-up phase. It asks me to press F1 or F2 to continue/configure bios settings, which is funny considering the keys don't work...
Anyway, reconnecting it to the USB seems fixes the problem, except the problem comes back when I boot into Windows, so I have to reconnect again. I have tried different USB ports, same problem. I never had this problem with a membrane keyboards, so I'm really confused as to why this is happening.
I have also flashed the BIOS to a newer version, but the problem persists when I boot into windows. I'm not sure what the next steps are...
I'd send this in for a replacement if I can somehow confirm it is a hardware issue...
