This is a weird USB error.

Sorry for all this trace, but I wanted to include all the relevant errors.

I had a USB2 thumb drive plugged into a USB2 port which I removed because..

I wanted to check whether this keyboard was recognized, after which I
unplugged it.

The result was these strange errors which led to me losing the keyboaard
and the mouse, which was plugged into its hub!  The keyboard was plugged
into a USB2 port to the right of the port where I'd plugged in the other
keyboard.

It looks like the removal of the second keyboard was not handled correctly.

I only got the keyboard and mouse back after plugging the keyboard into
a USB3 hub.

Interestingly, I could then plug a USB thumb drive into one of the
USB2 ports and it was recognized, but trying to plug the keyboard into
the adjacent USB2 port resulted in lots of errors and I had to plug it
back into the USB3 hub.

So, it almost appears that having two USB keyboards plugged into USB2
ports, and then removiing one,  resulted in the errors.
