  42. .Sh DESCRIPTION
    43. 

  43. Attach a device to the system after the
    44. 

  44. .Fn DEVICE_PROBE
    45. 

  45. method has been called and has indicated that
    46. 

  46. the device exists.
    47. 

  47. The
    48. 

  48. .Fn DEVICE_ATTACH
    49. 

  49. method should initialize the hardware and allocate other
    50. 

  50. system resources (such as
    51. 

  51. .Xr devfs 5
    52. 

  52. entries).
    53. 

  53. .Pp
    54. 

  54. Devices which implement busses should use this method to probe for
    55. 

  55. the existence of devices attached to the bus and add them as
    56. 

  56. children.
    57. 

  57. If this is combined with the use of
    58. 

  58. .Xr bus_generic_attach 9
    59. 

  59. the child devices will be automatically probed and attached.
