Having given it a bit more thought, I don't think that this is a scenario that
the USB protocol can be guaranteed to handle cleanly - there is too much
low-level bus state involved. I think the safest approach is to detect
disconnection from the host by monitoring the USB bus power line and using this
as a trigger to restart the USB interface ready for a clean connection to the
new host.
