.In sys/bus.h
.Ft void
.Fn BUS_NEW_PASS "device_t dev"
.Sh DESCRIPTION
The
.Fn BUS_NEW_PASS
method is called on each bus device to rescan the device tree when the pass
level has been changed.
This method is responsible for invoking
.Xr BUS_NEW_PASS 9
on child bus devices to propagate the rescan to child devices.
It is also responsible for reprobing any unattached child devices and
allowing drivers for the current pass to identify new children.
A default implementation is provided by
.Xr bus_generic_new_pass 9 .
