Question Easiest way to know if a VR device is connected

Hello,

I am currently working on an application using OpenXR. I wanted to be able to start the appliation in desktop mode when no VR device is found. I tried to achieve that using UnityEngine.XR.InputDevices.

Code (CSharp):

1.  
2.         var inputDevices = new List<UnityEngine.XR.InputDevice>();
3.         UnityEngine.XR.InputDevices.GetDevices(inputDevices);
4.         Debug.Log(inputDevices.Count);
5.  
6.  
7.         foreach (var device in inputDevices)
8.         {
9.             Debug.Log(string.Format("Device found with name '{0}' and role '{1}'", device.name, device.characteristics.ToString()));
10.         }
11.  

Problem is that when I start the application in the Editor whith my HP Reverb G2 connected it starts correctly using the headset but my list of input device is empty. Did I miss something or is there a simpler way to do that ?
