firmata_test only works with StandardFirmata.
Servo.h must be removed from StandardFirmata.ino. After the corrections it will be able to compile in Arduino IDE 1.5.1.
Then firmata_test began to show controls with Due board.
I think (this is just my guess) that firmata_test need to devote more time to get a list of the initial capabilities to show all controls without missing Pins. Increasing the value of SamplingInterval not helping for Due.
