This happened to me too, back in January. It managed to fry two different U2F devices as well as a cable, which were plugged into different ports. One of the devices got so hot before I noticed it that it actually melted the plastic on the U2F device itself. Fortunately, it was my work laptop, and my company was able to replace it, but at best it's inconvenient to have to replace a machine, and it's kind of frightening to suddenly smell burning plastic in your home.
