Almost all systems use one of the IDs we do support as a _CID if not a _HID.
In fact, in this case it likely seems to be a BIOS bug as it used the same
value for the _CID and _HID. I suspect it is supposed to be using 0303 as its
_CID.

Note that 030B is listed as reserved in this table, and not a valid keyboard
device.
