I don't think I have a patch for the MX1000 among them. I do have the
MX1000, though, and I'm still thinking about what to do with it.

The problem is that the mouse really does reports all the double-button
stuff and autorepeat, and horizontal wheel together with button press on
wheel tilt.

It has all that in the report descriptor, and the HID driver correctly
interprets it and passes it on.

It's annoying, though.

I could kill the extra buttons (via a HID quirk), which would leave us
with autoscroll up/down/left/right, but the wheel wouldn't be
distinguishable from the autoscroll anymore.

I can't kill the autoscroll alone and leave the buttons, because again
the driver can't easily tell if it's the wheel or not.

In the end I think the best option is to leave the filtering to
userspace, which will mean more configuration necessary in the X event
mouse driver.
