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.
