  49  *  \section Sec_Description Project Description:
  50  *
  51  *  Dual Communications Device Class demonstration application.
  52  *  This gives a simple reference application for implementing
  53  *  a compound device with dual CDC functions acting as a pair
  54  *  of virtual serial ports. This demo uses Interface Association
  55  *  Descriptors to link together the pair of related CDC
  56  *  descriptors for each virtual serial port, which may not be
  57  *  supported in all OSes - Windows Vista is supported, as is
  58  *  XP (although the latter may need a hotfix to function).
  59  *
  60  *  Joystick actions are transmitted to the host as strings
  61  *  through the first serial port. The device does not respond to
  62  *  serial data sent from the host in the first serial port.
  63  *
  64  *  The second serial port echoes back data sent from the host.
  65  *
  66  *  After running this demo for the first time on a new computer,
  67  *  you will need to supply the .INF file located in this demo
  68  *  project's directory as the device's driver when running under
  69  *  Windows. This will enable Windows to use its inbuilt CDC drivers,
  70  *  negating the need for custom drivers for the device. Other
  71  *  Operating Systems should automatically use their own inbuilt
  72  *  CDC-ACM drivers.
  73  *
