On my desktop, I do not list any mouse in xorg.conf, and let the X
server find the mouse when I start. It handles plugging in or
removing my wireless mouse just fine. It even manages to handle
plugging in the wireless  mouse after starting X.

On my Toshiba laptop, I have:

Section "InputDevice"
        Identifier  "Synaptics"
        Driver      "synaptics"
        Option      "Device" "/dev/input/mice"
        Option      "Protocol" "auto-dev"
        Option      "Emulate3Buttons" "yes"
EndSection

to handle the build-in touch-pad. I can still plug a wireless mouse
in after booting and it does not have a problem - both the mouse and
the touch-pad work.

So you may want to remove the mouse section, and see how things work
that way. You may also want to check your BIOS setting to see if it
is set to disable the laptop mouse when you plug another mouse in.
Because one thing that I have notices sometimes bothers X is when
you change the mouse type after you have started the X server.
Adding or removing a mouse is fine, but changing the protocol the
mouse uses is not. (Sometimes a problem when using KVM switches.)
