All my USB ports stop working and I need to cold boot to get them back.
I _was_ running my mouse through the hub in my monitor. Now I've removed it from the hub, and will test with nothing running off the hub. Failing that, I will unplug the hub. It would be a shame, because the hub worked perfectly for years on older machines with earlier Ubuntu versions.
