Yes. USB devices are polled, but USB mass storage disk fobs are
_horrible_ at being well behaved.

In the general section you will find a note about that some devices
need a few seconds after enumeration before you can send them a
command.  Some of these devices may just crash if you do not pause.
But I've not seen that particular problem yet.   Perhaps it was just
with older fobs.
