Hey @stvnxu,
I bought yesterday Elite Dangerous as well and have already the Vive Cosmos. I can start the game with the Cosmos headset, but I can't use my Cosmos controllers, because they are not recognised in the game.
They are working fine with every other programme or game. I had the same/ a similar problem with No Man's Sky, but there the controller recognition was fixed.
Do you (or somebody else) have any idea, how I can use my Cosmos controllers with Elite Dangerous? I don't want to buy a HOTAS.
Greetings
Muerto
