I suppose not. HID is more or less gibberish to me but at least I haven't
seen any extra keyboard events from the mouse or anything like that. The
mouse has just two buttons and a vertical wheel. The keyboard has the normal
keys, volume and playback control keys and some 10 extra keys like sleep,
mail, web etc. It also has an f-lock key which I suppose has something to
do with the fact that they've re-labeled the function keys with some
web/email/whatever texts and the F<number> is printed on the side
of the key.

I've used the device so little that I honestly didn't even notice that
the mouse claims to support pretty much every kind of event there is.
Maybe they were just lazy when making this device and didn't want to think
about the actual features of the device and instead just added every
possible thing to the descriptors.
