You could try experimenting with "USB Legacy Support"
in the BIOS. I'm not really sure whether your problem
is related to OS support for your mouse, or this is
a problem with device detection on the USB bus. Some
USB problems, of the disconnect/reconnect type, appear
to be power management related, but some people never
manage to fix them. If the mouse works all the time
after being plugged in, then it probably isn't
power management related.

Maybe if you have installed a driver for the Logitech Trackball,
that driver is interfering with the ability to have multiple
pointing devices connected ? What happens if the Trackball
driver is removed - can WinXP still get basic functionality
from the Trackball ?
