The HID Subclass 1 defines two descriptors for Boot Devices. Devices may
append additional data to these boot reports, but the first 8 bytes of keyboard
reports and the first 3 bytes of mouse reports must conform to the format defined
by the Boot Report descriptor in order for the data to be correctly interpreted by
the BIOS.
