NAME
     BUS_RESCAN — rescan a bus checking for devices that have been added or removed


SYNOPSIS
     #include <sys/param.h>
     #include <sys/bus.h>

     void
     BUS_RESCAN(device_t dev);


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.
