Steam VR - Upper left corner with the 3 lines.
Click it - select Devices - Controller settings.
Choose Skyrim VR as your application.
Top right select current controller Vive cosmos.
Now press Edit at the top left where it says Current Binding Vive Cosmos Controller Legacy Bindings.
You're now in a window that says Legacy Bindings (Handed). Next to that there is a tab that says Set Up Legacy Actions. Click it.
Above the action aliases there is a little rectangular that says None Pretend to be this type of Controller.
Click that rectangular that says None and select Oculus Touch.
At the bottom click Save Personal Binding.
Enjoy the game.
P.S If you have controlmapvr.txt in SkyrimVR/Data/Interface/Controls/PC you need to delete it or it will override.

PS 之前有用过controlmapvr.txt 放在SkyrimVR/Data/Interface/Controls/PC 玩过的 请删除这个 不然会覆盖
此方法应该可以适用于所有不能识别的VR游戏，由于在上班还没测试，晚上回去试，有朋友试过的可以说下结果
