* usb_device_state: add idle_rate, led and protocol Previously all usb drivers and platform implementations (expect for our oddball atsam) tracked the same two global variables: - keyboard_protocol: to indicate if we are in report or boot protocol - keyboard_idle: for the idle_rate of the keyboard endpoint And a local variable that was exposed trough some indirection: - keyboard_led_state: for the currently set indicator leds (caps lock etc.) These have all been moved into the usb_device_state struct wich is accessible by getters and setters. This reduces code duplication and centralizes the state management across platforms and drivers. Signed-off-by: Stefan Kerkmann <karlk90@pm.me> * usb_device_state: reset protocol on reset The usb hid specification section 7.2.6 states: When initialized, all devices default to report protocol. However the host should not make any assumptions about the device’s state and should set the desired protocol whenever initializing a device. Thus on reset we should always do exactly that.

TMK Keyboard Firmware Core Library
This is a keyboard firmware library with some useful features for Atmel AVR and Cortex-M.
Source code is available here: https://github.com/tmk/tmk_keyboard/tree/master/tmk_core
Updates
2016/02/10
flabbergast's Chibios protocol was merged from https://github.com/flabbergast/tmk_keyboard/tree/chibios. See protocol/chibios/README.md. Chibios protocol supports Cortex-M such as STM32 and Kinetis.

Debugging
Use PJRC's hid_listen to see debug messages. You can use the tool for debug even if firmware use LUFA stack.
You can use xprintf() to display debug info on hid_listen, see common/xprintf.h.
