That fails during QEMU initialization with:
qemu-system-x86_64: -device usb-kbd,bus=myehci.0: Warning:
speed mismatch trying to attach usb device "QEMU USB Keyboard" (full
speed) to bus "myehci.0", port "1" (high speed)
qemu-system-x86_64: -device usb-kbd,bus=myehci.0: Device
initialization failed.
qemu-system-x86_64: -device usb-kbd,bus=myehci.0: Device 'usb-kbd'
could not be initialized
So I guess OVMF doesn't have a chance to get involved here before we
crash and burn :)
Thanks,
