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.
