Correct.  diskdruid doesn't go past the hub.  If you directly connect
the drive to a USB port, it should work.

If you open up ALT-F3 (or whatever console has the shell prompt) and do
a "lsusb", you'll see the ID numbers and names of the devices.  Then use
"lsusb -t", you'll see the tree of the USB system.  diskdruid won't go
below the first branches on those trees.
