- *
- *  The following list indicates what microcontrollers are compatible with this demo.
- *
- *  \li Series 7 USB AVRs (AT90USBxxx7)
- *
- *  \section Sec_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>Host</td>
- *   </tr>
- *   <tr>
- *    <td><b>USB Class:</b></td>

- *    <td>Full Speed Mode</td>
- *   </tr>
- *  </table>
- *
- *  \section Sec_Description Project Description:
- *
- *  CDC host demonstration application. This gives a simple reference application
- *  for implementing a USB CDC host, for CDC devices using the standard ACM profile.
- *
- *  This demo prints out received CDC data through the serial port.
- *
- *  Note that this demo is only compatible with devices which report the correct CDC
- *  and ACM class, subclass and protocol values. Most USB-Serial cables have vendor
- *  specific features, thus use vendor-specific class/subclass/protocol codes to force
- *  the user to use specialized drivers. This demo is not compatible with such devices.
- *
- *  \section Sec_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>
