Kingston USB3.0 Media Reader vs. "CCB request completed with an error" and the like during boot

From a head -r333133 boot of a Ryzen Threadripper 1950X
(native FreeBSD boot, not my usual Hyper-V boot):

uhub3: 22 ports with 22 removable, self powered

I'm not sure what to make of the (probe0:umass-sim0:0:0:0) notes.
For what I have used the Kingston USB3.0 Media Reader for, it
seems to work.
