The error numbers don't matter, apparently.
It's merely a hardware bug: there's too much current for the usb hub (as
I understand it with my limited knowledge of hardware). So we unplug
the hub, we wait a minute or two for the current to clear up, and we
replug everything. Problem solved.
Many thanks to this Mr. Paui Philippov!
