在UE5.3之后的版本，我个人发现把OpenXR、OpenXRViveTracker、LiveLink和LiveLinkXR插件都加上，仍然无法在LiveLink面板连接上ViveTracker以及Valve Index的控制器，哪怕SteamVR都已经完全识别所有的追踪器和控制器。后来找了很久才找到这个方法，希望对各位有帮助。

In versions after UE5.3, I personally found that adding OpenXR, OpenXR ViveTracker, LiveLink, and LiveLinkXR plugins still cannot connect ViveTracker and Valve Index controllers to the LiveLink panel, even though SteamVR has fully recognized all trackers and controllers. I searched for a long time later to find this method, hoping it would be helpful to everyone.
