bool viveWorkaround;

public override void InputDrop(bool isTrue, UdonInputEventArgs args) {

Debug.Log(viveWorkaround);

}

Attempt 1:

void Start() {

viveWorkaround = InputManager.GetLastUsedInputMethod() == VRCInputMethod.Vive;

}

Attempt 2:

public override void OnInputMethodChanged(VRCInputMethod inputMethod) {

viveWorkaround = inputMethod == VRCInputMethod.Vive;

}
