    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.
