Complete loss of XR input in 2020.1 except for 'isTracked'

Migrated to 2020.1 + XR Plugin Manager package + OpenVR XR Plugin.

Noticed button inputs stopped working with Index && Vive controllers.
Ran this debugging function and the only boolean output is "isTracked = true" ...so no buttons.
There are also no float values...so no joysticks, trigger squeezes, etc.

Tracking still works.
Any features with Vectors are still present and working.

Code (CSharp):

1.     private void DebugXRFeatures()
2.     {
3.         List<InputDevice> inputDevices = new List<InputDevice>();
4.         InputDevices.GetDevices(inputDevices);
5.  
6.         foreach (InputDevice device in inputDevices)
7.         {
8.             UnityEngine.Debug.Log(device.name);
9.  
10.             List<InputFeatureUsage> featureUsages = new List<InputFeatureUsage>();
11.  
12.             device.TryGetFeatureUsages(featureUsages);
13.  
14.             foreach (InputFeatureUsage featureUsage in featureUsages)
15.             {
16.                 UnityEngine.Debug.Log(featureUsage.name);
17.  
18.                 if (featureUsage.type == typeof(bool))
19.                 {
20.                     bool boolValue;
21.  
22.                     if (device.TryGetFeatureValue(featureUsage.As<bool>(), out boolValue))
23.                     {
24.                         UnityEngine.Debug.Log(string.Format($"Bool feature '{featureUsage.name}' = {boolValue}"));
25.                     }
26.                 }
27.                 else if (featureUsage.type == typeof(float))
28.                 {
29.                     float floatValue;
30.  
31.                     if (device.TryGetFeatureValue(featureUsage.As<float>(), out floatValue))
32.                     {
33.                         UnityEngine.Debug.Log(string.Format($"Float feature '{featureUsage.name}' = {floatValue}"));
34.                     }
35.                 }
36.                 else if (featureUsage.type == typeof(Vector3))
37.                 {
38.                     Vector3 vector3Value;
39.  
40.                     if (device.TryGetFeatureValue(featureUsage.As<Vector3>(), out vector3Value))
41.                     {
42.                         UnityEngine.Debug.Log(string.Format($"Vector3 feature '{featureUsage.name}' = {vector3Value}"));
43.  
44.                     }
45.                 }
46.             }
47.         }
48.     }

 

Yeah... it seems that the UnityXR Plugin Management system doesn't work with those anymore... except for oculus, still works for me..

For now I'm using SteamVR plugin for Vive/Index and Oculus Plugin/UnityXR for Oculus

 

I'm also running into this issue on 2019.4.11

 

Still not working in 2020.3.12f1. Has anyone heard anything, will this ever get fixed?
