DESCRIPTION

       The  BUS_RESCAN()  method is called to request a rescan of the child devices on a bus device.  The method
       should add any devices that have been added since the previous scan and remove  devices  that  have  been
       removed.   This  method  is  not required to re-examine existing devices to determine if their properties
       have changed.  This method is also not required to propagate the rescan request to child devices.
