The concept of "waiting for settle" doesn't make sense anyway.
USB devices are polled, correct?. So if you've got nothing better to
do than wait on it you should be able to poll until it's ready. What
does waiting for a random amount of time have to do with it?
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.
