In lufa-LUFA-140302/LUFA/Drivers/Peripheral/XMEGA/TWI_XMEGA.c it looks like the capitalization of twi (in the function body) vs TWI (arguments) is mismatched.
Causes compilation errors like "XMEGA TWI_XMEGA.c - error: 'twi' undeclared (first use in this function)".
The code compiles once the capitalization is normalized.
