Polling analogs / buttons in inControl system

Hello, I usually use unity3d with the input manager, but I got a new gamepad and decided to have a go with inControl library (https://github.com/pbhogan/InControl)

In order to get the value of buttons / analogs (I'm using generic controller) I have tried:

     using UnityEngine;
     using System.Collections;
     using InControl;
 
     public class pax2 : MonoBehaviour {
 
     // Use this for initialization
     void Start () {
         InputManager.Setup();
     }
     
     // Update is called once per frame
     void Update () {
         InputManager.Update();
         Debug.Log ("Analog [1]: "+ InputManager.Devices[1].Analogs[1].Value ); // get analog 1 value
     }
 }

Values are reported back ok only the first time, afterwards they seem to be stuck. What am I missing?

Thanks in advance.
