ahh, same thing here still, mapping works sort of doing it from ONLY the button next to the leap drop down, buttons just wont work in steamvr anything, and the psuedo vive mode gives me vive controllers in steamvr home, but in the dashboard or anything else, i get steam controllers still, all it did was switch them from oculus controllers to vive in steamvr home exclusively. if its any identifier, sometimes the buttons work, but ONLY the system button, and it usually only performs the walkinvr actions like move or rotate, i cannot replicate the issue. also once i got all the buttons to bind, but they all bound to the system button, this time they all opened the dashboard, disabling dashboard made them stop working, i was also unable to replicate this.
