NAME

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

SYNOPSIS

In sys/param.h In sys/bus.h Ft void Fn BUS_RESCAN device_t dev

DESCRIPTION

The Fn BUS_RESCAN method is called to request a rescan of the child devices on a bus device.

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.
