Can you show the log messages from running that command?
When I tested it with a USB flash drive, it disconnected from the USB
bus and trying the rescan idea didn't do anything.
That sounds like what I see.
I messed around
enough that I confused that USB controller and that entire bus was dead.
Fortunately, I managed to reset the controller and got it back by
telling the driver to remove it and then add it back.
How did you do that? Did it involve physically pulling and reinserting
the drive?
FWIW, this is what happens when I power on the dock:
