Debian                                          January 15, 2017                                DEVICE_ATTACH(9)

       Attach  a device to the system after the DEVICE_PROBE() method has been called and has indicated that the
       device exists.  The DEVICE_ATTACH() method should initialize  the  hardware  and  allocate  other  system
       resources (such as devfs(5) entries).

       Devices  which  implement  buses 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  bus_generic_attach(9)  the  child
       devices will be automatically probed and attached.
