I get these if I unplug an USB disk while still mounted. Could that be

then the driver will just reject the read/write there)

It lists only the ones "alive", not dead.

I  got this to  an internal USB card reader.
It used to shut off and only a system restart would fix it.
I never got it to work right so I took it out.
