*
* The following list indicates what microcontrollers are compatible with this demo.
*
* - Series 7 USB AVRs
* - Series 6 USB AVRs
* - Series 4 USB AVRs
* - Series 2 USB AVRs
*
* \section SSec_Info USB Information:
*
* The following table gives a rundown of the USB utilization of this demo.
*
* <table>
* <tr>
* <td><b>USB Mode:</b></td>
* <td>Device</td>

* <td><b>USB Class:</b></td>
* <td>Miscellaneous Device Class</td>

*
* \section SSec_Description Project Description:
*
* Dual Communications Device Class demonstration application.
* This gives a simple reference application for implementing
* a compound device with dual CDC functions acting as a pair
* of virtual serial ports. This demo uses Interface Association
* Descriptors to link together the pair of related CDC
* descriptors for each virtual serial port, which may not be
* supported in all OSes - Windows Vista is supported, as is
* XP (although the latter may need a hotfix to function).
*
* Joystick actions are transmitted to the host as strings
* through the first serial port. The device does not respond to
* serial data sent from the host in the first serial port.
*
* The second serial port echoes back data sent from the host.
*
* After running this demo for the first time on a new computer,
* you will need to supply the .INF file located in this demo
* project's directory as the device's driver when running under
* Windows. This will enable Windows to use its inbuilt CDC drivers,
* negating the need for custom drivers for the device. Other
* Operating Systems should automatically use their own inbuilt
* CDC-ACM drivers.
*
* \section SSec_Options Project Options
*
* The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
*
* <table>
* <tr>
* <td>
* None
* </td>
