wheel mouse problems


I have an Msoft Intellimouse 1.0A USB/PS2 mouse. I have a
/etc/system/trap/input. file below :-
kbd fd -d/dev/kbd ps2 mousedev

Now with the above line the mouse and the scroll wheel works fine. If I have
two separate lines like :-
kbd fd -d/dev/kbd
ps2 mousedev

The mouse works but no scroll wheel. Now if I use the following lines when I
have the USB mouse driver running :-
kbd fd -d/dev/kbd msoft fd -d/dev/usbmouse0

I again can get the mouse working but no scroll wheel. Now there is a -i
option to say you have a scroll wheel i.e :-
kbd fd -d/dev/kbd msoft -i fd -d/dev/usbmouse0

I get no mouse movement at all.

Any ideas as to what I’m doing wrong ? I’m trying to get this going on my
laptop which only has a USB mouse, its
just frustrating having always used the scroll mouse and then not being able
to…actually the laptop does have a
ps2 mouse but thats the touch pad…

TIA, Brett.
