Audio port connections... not default

I want to send audio from Cantbile to the Zedi 3/4 usb port.
But I have no idea how to get the port listed, and connected to.
The Voicemeeter Aux is the default device (software).
All other ports are enabled.
The Zedi is the a hardware mixer. Connected via usb / asio.
The Voicemeeter is used for EQ, and volume via knob.
Suggestions?
