      Properties not inherited from the base binding file.

      .. list-table::
         :widths: 1 1 4
         :header-rows: 1

         * - Name
           - Type
           - Details

         * - ``interface-name``
           - ``string``
           - .. code-block:: none

                HID device name. When this property is present, a USB device will use it
                as the string descriptor of the interface.



         * - ``protocol-code``
           - ``string``
           - .. code-block:: none

                This property corresponds to the protocol codes defined in Chapter 4.3
                of the HID specification. Only boot devices are required to set one of
                the protocols, keyboard or mouse. For non-boot devices, this property is
                not required or can be set to none.
                - none:     Device does not support the boot interface
                - keyboard: Device supports boot interface and keyboard protocol
                - mouse:    Device supports boot interface and mouse protocol



             Legal values: ``'none'``, ``'keyboard'``, ``'mouse'``

         * - ``in-report-size``
           - ``int``
           - .. code-block:: none

                The size of the longest input report that the HID device can generate.
                This property is used to determine the buffer length used for transfers.



             This property is **required**.

         * - ``in-polling-period-us``
           - ``int``
           - .. code-block:: none

                Input or output type reports polling period in microseconds. For USB full
                speed this could be clamped to 1ms or 255ms depending on the value.



             This property is **required**.

         * - ``out-report-size``
           - ``int``
           - .. code-block:: none

                The size of the longest output report that the HID device can generate.
                When this property is present, a USB device will use out pipe for output
                reports, otherwise control pipe will be used for output reports.



         * - ``out-polling-period-us``
           - ``int``
           - .. code-block:: none

                Output type reports polling period in microseconds. For USB full
                speed this could be clamped to 1ms or 255ms depending on the value.
                This option is only effective if the out-report-size property is defined.





   .. group-tab:: Deprecated node specific properties

      Deprecated properties not inherited from the base binding file.

      (None)

   .. group-tab:: Base properties

      Properties inherited from the base binding file, which defines
      common properties that may be set on many nodes. Not all of these
      may apply to the "zephyr,hid-device" compatible.

      .. list-table::
         :widths: 1 1 4
         :header-rows: 1

         * - Name

           - .. code-block:: none

                Property to identify that a device can be used as wake up source.

                When this property is provided a specific flag is set into the
                device that tells the system that the device is capable of
                wake up the system.

                Wake up capable devices are disabled (interruptions will not wake up
                the system) by default but they can be enabled at runtime if necessary.



         * - ``power-domain``
           - ``phandle``
           - .. code-block:: none


                Power domain the device belongs to.

                The device will be notified when the power domain it belongs to is either
                suspended or resumed.



         * - ``zephyr,pm-device-runtime-auto``
           - ``boolean``
           - .. code-block:: none

                Automatically configure the device for runtime power management after the
                init function runs.
