Вот пример обмена:

the hardware is implemented correctly, and you properly initialize the 'D12,
then connect the cable, you should expect to see something similar
to the following sequence of events...

Your enumeration sequence may be quite different... it changes for different devices,
and from OS to OS. This is one of the reasons I made my comment about your code needing to be "event driven" instead of linear.
