Ok here is what happens,
In your system you have your touchpad declared both in a static way in
your xorg config, and probed by HAL.
What happens is that when xorg starts it first install the touchpad as
required by the config file, and then tries to install it again via
autodetection. Of course the second installation of the same device
doesn't work as the device is already busy with xorg, and xorg stops to
try to auto-install devices.
When you plug another mouse, xorg is notified that there are new
devices, but starts by trying to reinstall the touchpad, fails again for
the same reason as above and stops trying.
In order to solve your problem you can try the following :
a) remove the touchpad lines from your xorg config. This way the
touchpad should be installed by auto detection. (simply comment it as
you might be needing it back soon)
b) forbid hal from probing the touchpad. If solution a fails, I would
explain to you how to do this if solution a) fails.
