Message:

Setting boot protocol for the keyboard, initialization in add_device().

• Moved initialization of kbd to add_device() function. If it fails, it doesn't start to poll the keyboard.
• Added setting of boot protocol to the keyboard in init_device().
• Added constants for protocols to libusb/classes/hid (and renamed interface protocol enum).
