I think you are asking for trouble trying to do this with asio4all. I have a Babyface pro fs and would never use anything but the solid rme drivers. I doubt you will find anyone trying to do what you are doing with asio4all. Even if you get it to work you could have problems with sync issues. That is why Cubase doesn’t support multiple audio interfaces. Asio4all is a bit of a bodge to get round it.
