    /// Base class for controllers made available through the Steam controller API.

    /// <remarks>
    /// Unlike other controllers, the Steam controller is somewhat of an amorphous input
    /// device which gains specific shape only in combination with an "In-Game Action File"
    /// in VDF format installed alongside the application. These files specify the actions
    /// that are supported by the application and are internally bound to specific controls
    /// on a controller inside the Steam runtime. The bindings are set up in the Steam client
    /// through its own binding UI.
    ///
    /// Note that as the Steam controller API supports PS4 and Xbox controllers as well,
    /// the actual hardware device behind a SteamController instance may not be a
    /// Steam Controller. The <see cref="steamControllerType"/> property can be used what kind
    /// of controller the Steam runtime is talking to internally.
    ///
    /// This class is abstract. Specific Steam controller interfaces can either be implemented
    /// manually based on this class or generated automatically from Steam IGA files using
    /// <see cref="SteamIGAConverter"/>. This can be done in the editor by right-clicking
    /// a .VDF file containing the actions and then selecting "Steam >> Generate Unity Input Device...".
    /// The result is a newly generated device layout that will automatically register itself
    /// with the input system and will represent a Steam controller with the specific action
    /// sets and actions found in the .VDF file. The Steam handles for sets and actions will
    /// automatically be exposed from the device and controls will be set up that correspond
    /// to each action defined in the .VDF file.
    ///
    /// Devices based on SteamController can be used in one of two ways.
    ///
    /// The first method is by manually managing active action sets on a controller. This is done by
    /// calling the various APIs (such as <see cref="ActivateSteamActionSet"/>) that correspond
    /// to the methods in the <see cref="ISteamControllerAPI">Steam controller API</see>. The
    /// controller handle is implicit in this case and corresponds to the <see cref="steamControllerHandle"/>
    /// of the controller the methods are called on.
    ///
    /// The second method is by using
    ///
    ///
    ///
    ///
    ///
    /// By default, Steam controllers will automatically activate action set layers in
    /// response to action maps being enabled and disabled. The correlation between Unity
    /// actions and action maps and Steam actions and action sets happens entirely by name.
    /// E.g. a Unity action map called "gameplay" will be looked up as a Steam action set
    /// using the same name "gameplay".
