Ah, no indeed these are not keycodes, as the header says, "Most of the keys/buttons are modeled after USB HUT 1.12" > What standard defines that 138 is HELP? Is this a linux specific > thing, or is it defined somewhere else? In that particular case it looks like it is in the USB standard. I don't know how good the coverage of the USB standard is, but I'd say that it is better than AT scancodes.
