  52 /// a single handheld.  This class also owns the only Usb::Device object

  54 /// device object.  This class owns the only SocketZero object as well,
  55 /// which is the object that any SocketRoutingQueue is plugged into
  56 /// if constructed that way.
  57 ///
  58 /// To use this class, use the following steps:
  59 ///
  60 ///     - Probe the USB bus for matching devices with the Probe class
  61 ///     - Create an optional SocketRoutingQueue object and create a
  62 ///             read thread for it, or use its default read thread.
  63 ///     - Pass one of the probe results into the Controller constructor
  64 ///             to connect to the USB device.  Pass the routing queue
  65 ///             to the Controller constructor here too, if needed.
  66 ///     - Create the Mode object of your choice.  See m_desktop.h
  67 ///             and m_serial.h for these mode classes.  You pass
  68 ///             your controller object into these mode constructors
  69 ///             to create the mode.
