>From what I understand, consumer control packets are completely separate
packets that cannot contain keyboard keypresses (totally different usage page
than keyboard keys, 0xC vs 0x7). Just confirmed at
https://deskthority.net/wiki/Media_key#USB

Pressing both volume buttons on my mouse results in the two keys
pressed-released in order. Some devices *might* support simultaneous presses of
multiple media keys, but I think in that case, we would just lose the extra key
presses.
