The world of Eucon always looks confusing to me, aren’t they locked via some authentication software? It seems a platform which is far more open to failure (reading all the unhappy reports here) and you’re never sure which devices work well with Cubase, some have large screen displays for example and different buttons/faders.
Mackie/MCU is far more universal as a controller and auto fader banking, as much as I’d like it, has never truly caused me a problem. But, I use the Mackie as the primary controller, rather than a slave to my mouse/onscreen navigation.
