You seem to be talking 2.4? In 2.6 you have an abstract input layer,
where you call register_input_device() and then input_report_key() for
these kinds of devices. You definitely are not supposed to call
handle_scancode() directly.

We're talking about another HID separation, separating the parser for
HID descriptors, as defined in the USB HID specification.
