Hi,

I recently purchased a cheap USB mouse/keyboard combination. If I plug
it in /dev/ums0 is created, I also can run moused -p /dev/ums0, but the
mouse will not move.

I upgraded to a recent -STABLE, so ums.c is version 1.70.2.2.
I compiled a kernel with options USB_DEBUG and set
hw.usb.ums.debug=3D9999.
With cat /dev/ums0 > /dev/null I can see the Debug Info on the console:
ums_intr: sc=3D0x19d5c00 status=3D13
ums_intr: data =3D 01 00 00 00 00 01
ums_intr: status=3D13

It seems that this mouse sends 1 extra byte before the usual data, just
like the MS Wireless Intellimouse 2.0, because data is like:
01 BUTTON X Y Z 01

But seems like ums_intr() returns on line 467, so I tried this:

It sort of works. If I run moused -p /dev/ums0 I can actually use that
mouse, BUT it moves jerky, I have to move the wheel two positions
to get one and when a button is pressed when the mouse stands still it
is not recognized. The mouse _must_ move for the button to get noticed.

Has anyone an idea what to try next?
Any help would be greatly appreciated!

Marius
