Mouse relative movement = 0?



Hi all!

I'm writing HID mouse support for a game, and everything's working fine, except for one little thing:
When the mouse has moved, and is held still, it never resets the delta movement to zero, but it keeps on reporting the last delta movement. As it is a (rather odd, I might add) requirement that I don't use any kind of event queue, it feels as if this is impossible? Or is there a way to detect a non-movement of the mouse?


Thanks in advance,
/Ivan
