7.1.5 Response to Hard Resets
Device operation during and after a Hard Reset is defined as follows:
Self-powered devices Should Not disconnect from USB during a Hard Reset
(see Section 9.1.2).
Bus powered devices will disconnect from USB during a Hard Reset due to the
loss of their power source.
Therefore it is necessary to know whether the port belongs to
a device which is self powered or bus powered. This change
adds "self-powered" flag to the connector class which present indicates
that the port belongs to a device that is self powered. Else it is
bus powered usb device.

These bindings allow to describe most known standard USB connectors
and it should be possible to extend it if necessary.
USB connectors, beside USB can be used to route other protocols,
for example UART, Audio, MHL. In such case every device passing data
through the connector should have appropriate graph bindings.
