* Remove LUFA files

* Update descriptions for newer version of LUFA

* Create PR6245.md

* Fix CDC(Serial) type errors

- *  \brief Digital button board hardware driver.
- *
- *  This file is the master dispatch header file for the board-specific Buttons driver, for boards containing
- *  physical pushbuttons connected to the microcontroller's GPIO pins.
- *
- *  User code should include this file, which will in turn include the correct Button driver header file for the
- *  currently selected board.
- *
- *  If the \c BOARD value is set to \c BOARD_USER, this will include the \c /Board/Buttons.h file in the user project
- *  directory.

- *  \section Sec_Buttons_Dependencies Module Source Dependencies
- *  The following files must be built with any user project that uses this module:
- *    - None
- *
- *  \section Sec_Buttons_ModDescription Module Description
- *  Hardware buttons driver. This provides an easy to use driver for the hardware buttons present on many boards.
- *  It provides a way to easily configure and check the status of all the buttons on the board so that appropriate
- *  actions can be taken.
- *
- *  If the \c BOARD value is set to \c BOARD_USER, this will include the \c /Board/Buttons.h file in the user project
- *  directory. Otherwise, it will include the appropriate built-in board driver header file.
- *
- *  For possible \c BOARD makefile values, see \ref Group_BoardTypes.
- *
- *  \section Sec_Buttons_ExampleUsage Example Usage
- *  The following snippet is an example of how this module may be used within a typical
- *  application.
- *
- *  \code
- *      // Initialize the button driver before first use
- *      Buttons_Init();
- *
- *      printf("Waiting for button press...\r\n");
- *
- *      // Loop until a board button has been pressed
- *      uint8_t ButtonPress;
- *      while (!(ButtonPress = Buttons_GetStatus())) {};
- *
- *      // Display which button was pressed (assuming two board buttons)
- *      printf("Button pressed: %s\r\n", (ButtonPress == BUTTONS_BUTTON1) ? "Button 1" : "Button 2");
- *  \endcode
