Quite right. And it can really wreak havoc on a USB bus. Another thing that most people don't know is that mouse devices can be set to spontaneously generate position reports, even when they're not being moved. Most conventional mice turn this "feature" off... many specialty mice leave the feature on. So your mouse is sitting there on the desk, not moving, and generating constant position reports. Very helpful. Not! ONE nice thing is that most USB mice are USB low speed or USB Full Speed devices. This means you can isolate their traffic by carefully choosing the USB Root Hub port that you plug the device into (and NOT putting them on a hub that's shared with other devices).
