Question Connection of the driver's pedal to the Unity Input System

Hello, I am trying to connect a Thrustmaster pedal to Unity with the new input system, but I am encountering a few problems. Mainly, this pedal does not have a controller, so it appears in the Unity debug as an unsupported (HID). I solved this by manually creating a registry in the input system, making it pass through a gamepad with the following code extracted from the Unity documentation.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using System.Runtime.InteropServices;
4. using UnityEditor;
5. using UnityEngine;
6. using UnityEngine.InputSystem;
7. using UnityEngine.InputSystem.DualShock;
8. using UnityEngine.InputSystem.Layouts;
9. using UnityEngine.InputSystem.LowLevel;
10. using UnityEngine.InputSystem.Utilities;
11.  
12. [InputControlLayout(stateType = typeof(MyDeviceReport))]
13. #if UNITY_EDITOR
14. [InitializeOnLoad]
15. #endif
16. public class MyDevice: InputDevice
17. {
18.     static MyDevice()
19.     {
20.         InputSystem.RegisterLayout<MyDevice>("PedalsSIM", new InputDeviceMatcher()
21.             .WithInterface("HID")
22.             .WithManufacturer("Thrustmaster")
23.             .WithProduct("Sim Pedals"));
24.  
25.     }
26.     [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
27.     static void Init() { }
28. }
29.  
30. [StructLayout(LayoutKind.Explicit, Size = 32)]
31. struct MyDeviceReport : IInputStateTypeInfo
32. {
33.     public FourCC format => new FourCC('H', 'I', 'D');
34.  
35.     [InputControl(name = "Throttle", layout = "Analog", format = "BYTE", offset = 2)]
36.     [FieldOffset(2)] public byte Throttle;
37.     [InputControl(name = "Clutch", layout = "Analog", format = "BYTE", offset = 4)]
38.     [FieldOffset(4)] public byte Clutch;
39.     [InputControl(name = "Brake", layout = "Analog", format = "BYTE", offset = 5)]
40.     [FieldOffset(5)] public byte Brake;
41. }
42.  

With this, I have been able to visualize it in the debug input, but I am not able to obtain information from this through the action input.

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.InputSystem;
3.  
4. public class MyController : MonoBehaviour
5. {
6.     public NewControls InputMaster { get; private set; }
7.     InputAction mAction1;
8.     private void Awake()
9.     {
10.         InputMaster = new NewControls();
11.         AddInputMasterEvents(InputMaster);
12.     }
13.     public void AddInputMasterEvents(NewControls input)
14.     {
15.         if (input != null)
16.         {
17.             mAction1 = input.pedals.a;
18.  
19.         }
20.     }
21.     private void Update()
22.     {
23.  
24.         Debug.Log($"{mAction1 != null} { (mAction1 != null ? (mAction1.ReadValue<float>() * 1000) : 0)}   ");
25.     }
26.  
27. }

How could I connect this device correctly? It's worth noting that it also appears in the Windows device manager, although it appears in the category of other devices, and even in the game manager it also appears and even I can see the values with which I press the pedals.

 

Found this on the interwebs, maybe it can help:
