* \section Sec_Compat Demo Compatibility:
*
* 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>Human Interface Device (HID)</td>

* USBIF HID Usage Tables</td>
* </tr>
* <tr>
* <td><b>Supported USB Speeds:</b></td>
* <td>Low Speed Mode \n
* Full Speed Mode</td>
* </tr>
* </table>
*
* \section Sec_Description Project Description:
*
* Keyboard host demonstration application. This gives a simple reference
* application for implementing a USB Keyboard host, for USB keyboards using
* the standard Keyboard HID profile. It uses a HID parser for the HID reports,
* allowing for correct operation across all USB keyboards. This demo supports
* keyboards with a single HID report.
*
* Pressed alpha-numeric, enter or space key is transmitted through the serial
* USART at serial settings 9600, 8, N, 1. On connection to a USB keyboard, the
* report items will be processed and printed as a formatted list through the
* USART before the keyboard is fully enumerated.
*
* Currently only single interface keyboards are supported.
*
* \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>
