Hi Dimitry,

first of all, no top-posting. I really mean it.

that should be changeable on the fly and we should just export the HID
descriptor for users. Putting the burden to boot into a different kernel
is painful and we don't want that. Hell, I don't want to boot a new
kernel to just get the HID descriptor.
