DUE board: how to read USB joystick from the native USB port

Using Arduino Programming Questions
1

Hi, I'm new to Arduino programming, but I'm having trouble reading from the USB native port on my Arduino DUE board.

I have a Cyborg PC Flight Stick v1 usb joystick connected to the native USB port on my DUE and I cannot detect any input from the joystick.

The program is as follows:

void setup() {
  // initialize serial:
  Serial.begin(9600);
  SerialUSB.begin(9600);
}

void loop() {
  // if there's any serial available, read it:
  while (SerialUSB.available() > 0) {
    Serial.println(SerialUSB.read());
    }
}

I can't seem to find any info on the SerialUSB class.
What am I doing wrong? Any help would be appreciated!

The only thing obvious is not posting in the forum dedicated to the DUE.
