37.Sh SYNOPSIS
38.In sys/param.h
39.In sys/bus.h
40.Ft int
41.Fn DEVICE_ATTACH "device_t dev"
42.Sh DESCRIPTION
43Attach a device to the system.
44The probe method will have been called and will have indicated that
45the device exists.
46This routine should initialise the hardware and allocate other
47system resources (such as devfs entries).

43Attach a device to the system.

45the device exists.
46This routine should initialise the hardware and allocate other
47system resources (such as devfs entries).
48.Pp
49Devices which implement busses should use this method to probe for
50the existence of devices attached to the bus and add them as
51children.
52If this is combined with the use of
53.Xr bus_generic_attach 9
54the child devices will be automatically probed and attached.
48.Sh RETURN VALUES
49Zero is returned on success, otherwise an appropriate error is returned.
