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.
It could be the hardware on the laptop of course. Do you have other usb equipment you could try on it? Alternatively if the laptop is new I wonder whether the usb hardware is not fully supported by the 12.10 kernel. It would interesting to try running it on the Saucy live image to see if it fails then. If it runs for hours before failing (on 12.10) then that could be tricky.
I've not noticed any other issues with USB on the laptop but I don't often connect USB devices to it, just occasionally a Kindle but that's just to recharge it really.
I've just upgraded the laptop to 13.04 so I'll see if that makes any difference.
It sometimes runs for only a few minutes, other times for an hour or two.
