When the OS (i.e. Win80) has started, all is running fine. No problem<br>
with keyboard anymore. In Bios-menu himself the keyboards works fine, too.<br>

Personally speaking, I had a problem with my system being unable to boot when my Yubikey (a OTP device that presents as a USB keyboard) was plugged in.
