Reviewed the diagram carefully.  The only issue I spotted was that the
+5VSUS line into the RTC charger comes from a yellow switching voltage
regulator, despite the RTC charger coloured green.  Either it has to
come from somewhere else, or the RTC charger has to be yellow, or the
switching regulator has to be green.  ;-)

On the individual USB switching, can this be done between the USB chip
and the socket?  Being able to switch external devices would have
significant educational benefit in electronics teaching.  Perhaps only
switch two of the three, leaving the full capability on one.
