Some games can't see the controllers

[valord]

Are there action.json and bindings_vive_cosmos_controller.json files I can download to place it into the folder so I can see the controllers.

@valord Do you mean Viveport content? If you're on Viveport - there should be valid action bindings for every single device listed as compatible. We QA each device

If you're talking more generally, SteamVR binding system is notoriously wonky af. You must use the action bindings specifically configured for that game - you can't use generic ones.
