Wheel mouse and KVM switch problem

[Dave M]

I am having a problem with the wheel on the mouse (either HP MS48 or 
Logitech MX310) connected to P/S 2 port through a KVM switch. The wheel 
stops working after I use a KVM switch (Slim KVM 4-port switch) to switch 
between my Ubuntu (v6.06.1) and my Windows (ME) system.

The mouse wheel continues to work on the Win-ME system after switching but 
the wheel quits working on the Ubuntu system. If I unplug and re-connect 
the mouse (while the KVM is switched to the Ubuntu system) it starts 
working again.

I used xev to look at the mouse events. I see the button 4 and 5 events 
(mouse wheel) are working before switching. After switching I see no clicks 
from the mouse wheel. But buttons 1, 2 and 3 still work.

If I use the Logitech mouse the scroll wheel quits producing events and the 
thumb buttons change from producing button 8 and button 9 events to both 
producing button 2 events. But buttons 1, 2 and 3 still work properly.

my /etc/X11/xorg.conf looks like this:

Section "InputDevice"
	Identifier	"Configured Mouse"
	Driver		"mouse"
	Option		"CorePointer"
	Option		"Device"		"/dev/input/mice"
	Option		"Protocol"		"ExplorerPS/2"
	Option		"Buttons"		"10"
	Option		"ZAxisMapping"		"4 5"
	Option		"Emulate3Buttons"	"false"
EndSection

I am not sure what to look at next.
