Ok, today I spent some time deciphering the ums log and came up
with this patch.

ibuf = sc->sc_ibuf;
- if (sc->sc_iid) {
- if (*ibuf++ != sc->sc_iid)
- return;
- }
+ if (sc->sc_iid)
+ ibuf++;
dx = hid_get_data(ibuf, &sc->sc_loc_x);
dy = -hid_get_data(ibuf, &sc->sc_loc_y);
Unfortunately my knowledge (or rather lack of it) of the USB/UMS
driver doesn't give me very much confidence that I didn't break
something else.
What was that conditional return suposed to protect from?
Is it safe to remove it?
The PS/2 mouse works now and the USB one as well.
Cheers,
