This is what I do when I suffer these types of problem, which is often by the way, and I have not found a correct way of fixing so it is temporarily at best.

I go to Device Manager, then to Universal Serial Bus Controllers and I start uninstalling the Generic USB Hubs and then the other hubs, hoping not to nuke my mouse, if I don't then I go to the Action Tab and click on Scan for Hardware changes and it will rearrange the usb drivers and IRQs in hopes that they do not clash with each other. If it does nuke the mouse then I manually restart the PC and hope that it will solve the issue once I am back at the desktop.

There is no damage done to the PC, at least I have not seen any real damage but until I find a better way, this is what I have to deal with.
