NAME
BUS_RESCAN - rescan a bus checking for devices that have been added or
removed
SYNOPSIS
#include <sys/param.h>
#include <sys/bus.h>

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.
