mouse: scroll wheel not working properly

[Jose Luis Rodriguez Garcia <joseyluis%gmail.com@localhost>]

I have bought a new mouse, and the scroll wheel changes of direction:

If I move up the wheel, the wheel moves up in the screen, but after of
a few moments, it reverses the direction: it goes down, The same thing
happes in the other direction.

I have tested with xev. When I scroll the wheel in a only direction,
it alternates between buttons 4 and 5.

If I scroll up the wheel xev: receives 10 hits from button "5", and
after 6 hits from button '4', and cycles:

10 times button "5", 6 times button "4", 10 times button "5", 6 times
button "4", 10 times button "5", ......


The model of mouse is: Maxtrack from Trust. web page: trust.com/17179-02

My NetBSD is 6.1.2./ amd64. I have tested with the last kernel of NetBSD 6.


pc2$ dmesg|grep wsmouse
wsmouse0 at ums0 mux 0
wsmouse1 at ums1 mux 0

wsmouse1 at ums1 mux 0
wsmouse0 at ums0 mux 0
wsmouse1 at ums1 mux 0
wsmouse0: detached
wsmouse0 at ums0 mux 0

This is the outpout of dmesg. wsmouse0 is the mouse. wsmouse1 is a
conversor from usb to ps2 keyboard and ps2 mouse.
