I have a Logitech wireless trackball that I use with my Acer Aspire netbook running Xubuntu 12.10. It works for quite a while (random amounts of time) and then stops, the following messages appear in syslog when it stops:-

An identical Logical trackball works perfectly with Xubuntu 12.10 on my desktop machine.
I would initially suspect a hardware fault. Swap the trackballs between the machines (including the receivers). That will tell you whether it is the machine or the trackball that is faulty. Also try different USB ports to see if it is a fault with one of the ports.
I originally saw the fault when I used the trackball from my desktop machine on the laptop, so both trackballs do it on the laptop and neither does on the desktop.
The trackball will work again if I plug the 'dongle' into the other port on the laptop but it fails again after a similar random period and then the only way to restore working is to reboot.
And what happens if you use a wireless mouse?
I've no idea, I don't have one. Though I can't see what difference it would make, the Logitech trackball is a perfectly standard 'mouse' from the computer's point of view.
