*
* <table>
* <tr>
* <td><b>USB Mode:</b></td>
* <td>Device</td>

*
* \section SSec_Description Project Description:
*
* This bootloader enumerates to the host as a HID Class device, allowing for Teensy compatible programming
* software to load firmware onto the AVR, such as the official software at <a>http://www.pjrc.com/teensy/</a>.
*
* Out of the box this bootloader builds for the ATMEGA32U4, and will fit into 2-4KB of bootloader space. For other
* devices, the makefile will need to be updated to reflect the altered MCU model and bootloader start address. When
* calculating the bootloader start address, use (TARGET_FLASH_SIZE_BYTES - 4096) for targets where the bootloader
* compiles larger than 2KB, or (TARGET_FLASH_SIZE_BYTES - 2048) for smaller targets where the bootloader compiles
* under 2KB.
*
* This spoofs (with permission) the official Teensy bootloader's VID and PID, so that the software remains
* compatible with no changes.
*
* \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.
