 // This class partners with DeviceController and has the same lifetime and
 // threading characteristics as DeviceListener. In a nutshell, this class
 // operates on its own thread and is destroyed on the thread it was constructed
 // on. The class' deletion can happen in two different ways:
 // - Its destructor was called by its owner (HostControllersManager).
 // - Its internal thread requested self-deletion after an error happened. In
 //   this case the owner (HostControllersManager) is notified on the
 //   construction thread through the provided ErrorCallback invoked with the
 //   HostController instance. When this callback is invoked, it's up to the
 //   owner to delete the instance.
