This is a very tricky sort of problem to solve. There's a good chance it's closely tied to your particular hardware. Have you tried using the same mouse on a different Linux computer? Another way of testing different hardware would be to buy or borrow a PCI add-on USB controller card and plug the mouse into that. > Is it worth reporting to bugzilla.kernel.org? Up to you. One advantage of a bugzilla entry is that all the information relating to the bug report is right there, in one place. People don't have to go searching through old email archives to fit all the pieces together. > I could allow access to the box for developers if that takes us any > closer to solving this...

Assuming you have built the USB host controller drivers uhci-hcd, ohci-hcd, and ehci-hcd as modules, you can rmmod all of them and then modprobe them back. (Hint: This works best if you rmmod ehci-hcd last and modprobe it first. In fact, you might want to check the system logs to make sure that ehci-hcd gets installed before the other two even at boot time.) This will reset all aspects of the bus except for the power; there's no way to turn off the power without unplugging the mouse.
