I have the same issue. I'm using the SteamVR null driver and I have the tracker working in Unity using the SteamVR plugin, but I'm only getting about 30 Hz updates.

(If my previous post with error messages goes through) I was able to fix it, I changed: HTCViveTrackerProfile.cs // line ~14 // Comment out: //using PoseControl = UnityEngine.XR.OpenXR.Input.PoseControl; // Change to: using PoseControl = UnityEngine.InputSystem.XR.PoseControl; Unity deprecated UnityEngine.XR.OpenXR.Input.PoseControl (it says so if you mouse over it in Visual Studio), they suggest UnityEngine.InputSystem.XR.PoseControl instead. Now I just need to keep something on my Oculus Quest 2's sensor to make it think a user is in the headset, and I receive tracking in Unity. Trying to figure out if I can eliminated the headset now.

Managed to get the trackers somewhat working in PC VR. I've joined the discord (https://discord.gg/viverse) to get access to the beta. I installed the Vive Streaming Hub (https://www.vive.com/us/support/vs/category_howto/using-vive-streaming.html). Paired & calibrated the tracker with the help of an Oculus Quest 2. Assigned the tracker as Camera in SteamVR. I logged in & followed the VIVE_Ultimate_Tracker_PC_OpenXR_v2.pdf, however, it is not working. I'm on Unity 2022.3.16, URP, OpenXR Plugin + Vive OpenXR. Added the HTC VIVE Tracker Profile C# script to the project: Created an Input Action asset and assigned the camera tracker: I get a warning: No GetDeviceLayoutName() override detected in HTC Vive Tracker Profile. Binding path validator for this interaction profile is not as effective. To fix, add GetDeviceLayoutName and GetInteractionProfileType override in this profile.

Is there really no way to use this without a headset? I'm trying to use the Vive Ultimate Tracker has a general purpose 3D tracker as a Windows application. If not I'm going to have to return it.
