Surface Pro X (sc8180x), but it should be similar enough to the X13s in
that regard. At least from what people with access to the X13s told me,
the qseecom stuff seems to behave the same.

Unfortunately I don't have a direct serial console. Best I have is
USB-serial, but it's not even getting there. I'll have to try and see if
I can get some more info on the screen.

Best regards,
Max
