Have a look in your /etc/X11/XF86Config-4.

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
        Option          "CorePointer"
        Option          "Device"                "/dev/psaux"
        Option          "Protocol"              "PS/2"
        Option          "ZAxisMapping"          "4 5"
EndSection

Section "InputDevice"
        Identifier      "Generic Mouse"
        Driver          "mouse"
        Option          "SendCoreEvents"        "true"
        Option          "Device"                "/dev/input/mice"
        Option          "Protocol"              "ImPS/2"
        Option          "ZAxisMapping"          "4 5"
EndSection

The relevant bits are Option "CorePointer" and Option "SendCoreEvents".
The USB trackball on /dev/input/mice can come or go as often as I want
it to (assuming that hotplugging is correctly configured, more in a bit)
without concern.  This is true on my desktop as it is true on my laptop.

To make sure that hotplugging is working, have a look at
/var/log/messages with tail (use tail -f).  Plug in the mouse and see if
the hotplugging daemon catches and reports the event.  If that doesn't
happen, report back and we'll tackle that avenue separately.
