Why would you want to use the mouse in native mode? There is no cursor
when a native mode application runs at the start of boot.

To read from keyboard in native mode you need to open a handle to
“\Device\KeyboardClass0” device and read KEYBOARD_INPUT_DATA buffers from
it.

That will not work for a couple of reasons. One, there may be more then
one physical keyboard and you will only be reading from one of them.
There are virtual keyboard stacks on the machine, especially for
terminal services. More often then not, the virtual keyboard is
\Device\KeyboardClass0 so in that case you will never see any keystroke.
Instead, get the list of keyboard device interfaces, open each one and
then pend a read on each device.
