try to add the following line in your XFree86Config-File in
Section "InputDevice"

Option "SendCoreEvents" "true"

for both Input Devices (Generic + Trackball).

Don´t forget to add the new mouse entry in Section "ServerLayout" ->

Section "ServerLayout"
Identifier "..."
InputDevice "..."
InputDevice "Generic Mouse"
InputDevice "Trackball"
