VIVE Cosmos controller mapping fix:
1) Download the replacement DLL from this link:
github.com/fholger/openvr/releases/download/fo4vr_v1.1/openvr_api.dll
2) Go to the Fallout 4 VR root
Typically C:\Program Files (x86)\Steam\steamapps\common\Fallout 4 VR
3) Backup the original openvr_api.dll file (optional)
4) Copy and paste the replacement openvr_api.dll file in the Fallout 4 VR root

Finally we get to go back to an HTC VIVE system with Fallout 4 VR, but this time we're using the Cosmos, which has controllers that have BUTTONS and THUMBSTICKS unlike the original VIVE wands which were god awful with their track pads and lack of buttons. In this description, above this text is a procedure that will help you fix the Fallout 4 VR controller mapping so Cosmos controllers don't register as VIVE wands (which makes the game impossible to play).
