Topic: Totalmix doesn't detect UCX II on macOS Catalina

Just received my UCX II, and after driver install I immediately had audio playback working on macOS 10.15.7 Catalina.

However, while Totalmix does open, it doesn't show any windows, and when I select File > New TotalMix Window, no devices are shown.

RME USB Series Flash Tool doesn't even open.

I installed the latest 10.5 driver (driver_usb_mac_3221.zip) + restarted 3 times.

Sounds like the UCX II is in Class Compliant mode. Turn this off at the unit by removing USB, then  SETUP/REV, Options, Hardware/Diagnosis, CC Mode Off.
