.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.
The probe method will have been called and will have indicated that
the device exists.
This routine should initialise the hardware and allocate other
system resources (such as devfs 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.
