Hi John,

I've included a proposed patch which adds the extra functionality to the USB
slave API, together with a modified version of the STM32 driver which makes use
of the additional API functionality.  These are for comment only, as they seem
to be OK but have not yet had a proper workout.

I've got a pretty demanding contract on at the moment, but I'll try and get
some proper testing in when I have the time and will report back when I'm happy
with the changes.  However, this will probably be with my proprietary class
driver rather than one of the standard eCos ones.  A patch against the standard
eCos serial driver will take a little longer.
