You can perhaps try to have both mice work all the time (even when the USB
mouse is plugged in), by having two mice. Look at your XF86Config-4 file:
it has parts looking like:

Section "ServerLayout"
.
        InputDevice    "Mouse0" "CorePointer"
.
EndSection
..
Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Device" "/dev/mouse"
        Option      "Protocol" "imPS/2"
        Option      "Emulate3Buttons" "off"
        Option      "ZAxisMapping" "4 5"
EndSection


You can add another mouse, Mouse1 (with a different "Device" option),
and then say that Mouse1 is an alternate pointer on that InputDevice line.
I don't remember the exact syntax - maybe you should read the docs or maybe
someone else can give a working example - but I tried it once and it worked:
I got both a PS2 mouse and a USB mouse to work on the same system concurrently.
I could even have the mice "fight" each other - you move the two mice, and
see which way the pointer ends up moving (obviously, even with two mice
you only end up with one pointer).
