    When using SIO for VBus monitor pin, is it ok to use resistive pulldown drive mode?

      The default mode is high impedance but this doesn't work well with a self powered device. If you pull the USB connector it can take a long time for the VBus line to drift low. It's a legal selection for the pin but don't want to cause any unwanted issues although I think an SIO is fairly hardy.
