is there a chance that you could try input-events on all the other input devices, and check if you get EV_KEY BTN_* events on any of them when you press a hotkey on that keyboard?
Since these don't come from input/event3 (the hotkey portion of the MS keyboard for you), they must come from somewhere else. After/if you found it, can you please tell us the number and copy&paste the ouput of "sudo lsinput"?
