Some other odd things. If we plug in a new UPS to the hub, it fails

usbd_setup_device_desc: getting device descriptor at addr 13 failed,

but, if we plug it in, then reboot the box, it seems to work.

The error seems to follow the first port of the second HUB that is
plugged in.

Also, unplugging and replugging a device gives
