Logitech USB Controller Programming Issues

[speckz]

We cannot get our Logitech USB controllers to work properly with our code in RobotC. The debugger picks up when buttons are pressed and joysticks are moved correctly but when the code is run the code will not pick up what is going on with the controller.

Here is the code:

#pragma config(Hubs,  S1, MatrxRbtcs, none,     none,     none)
#pragma config(Sensor, S1,     ,               sensorI2CMuxController)
#pragma config(Motor,  mtr_Matrix_S1_1, motorD,        tmotorTetrix, openLoop)
#pragma config(Motor,  mtr_Matrix_S1_2, motorE,        tmotorTetrix, openLoop)
#pragma config(Motor,  mtr_Matrix_S1_3, motorF,        tmotorMatrix, openLoop)
#pragma config(Motor,  mtr_Matrix_S1_4, motorG,        tmotorMatrix, openLoop)
#pragma config(Servo,  srvo_Matrix_S1_1, servo1,               tServoNone)
#pragma config(Servo,  srvo_Matrix_S1_2, servo2,               tServoNone)
#pragma config(Servo,  srvo_Matrix_S1_3, servo3,               tServoNone)
#pragma config(Servo,  srvo_Matrix_S1_4, servo4,               tServoNone)
//*!!Code automatically generated by 'ROBOTC' configuration wizard               !!*//

#include "JoystickDriver.c"

task main()
{
  servo[servo1] = -127;
  wait1Msec(500);

  while (true)
  {
  	getJoystickSettings(joystick);
  	if(joy1Btn(00) == true)
  		servo[servo1] = 127
  }
}

This is a matrix robot for the First Tech Challenge. Moving motors and servos normally works fine but when we try to do it with a USB controller the code does not pick anything up.
We are using NXT brick which has the correct firmware from RobotC 4.26.

What might we be doing wrong? Thank you.
