<p class="Pp">This function provides an implementation of the
    <a class="Xr">BUS_NEW_PASS(9)</a> method which can be used by bus drivers.
    It first invokes the <a class="Xr">DEVICE_IDENTIFY(9)</a> method for any
    drivers whose pass level is equal to the new pass level. Then, for each
    attached child device it calls <a class="Xr">BUS_NEW_PASS(9)</a> to rescan
    child buses, and for each unattached child device it calls
    <a class="Xr">device_probe_and_attach(9)</a>.</p>
