+.Sh NAME
+.Nm DEVICE_ATTACH
+.Nd attach a device
+.Sh SYNOPSIS
+.In sys/param.h
+.In sys/bus.h
+.Ft int
+.Fn DEVICE_ATTACH "device_t dev"
+.Sh DESCRIPTION
+Attach a device to the system after the
+.Fn DEVICE_PROBE
+method has been called and has indicated that
+the device exists.
+The
+.Fn DEVICE_ATTACH
+method should initialize the hardware and allocate other
+system resources (such as
+.Xr devfs 5
+entries).
+.Pp
+Devices which implement busses should use this method to probe for
+the existence of devices attached to the bus and add them as
+children.
+If this is combined with the use of
+.Xr bus_generic_attach 9
+the child devices will be automatically probed and attached.
+.Sh RETURN VALUES
+Zero is returned on success, otherwise an appropriate error is returned.
