OB 2 won't see Analog 4 - Latest OSX Mojave/OB/OS

Tearing my hair out over my inability to get my A4 to be seen in Overbridge.

Says measuring for about 10 seconds, then responds with Fault.

Mojave 10.14.6
Latest Overbridge 2
Latest A4 OS
Overbridge mode

Driver is loaded and viewable under Applications in System prefs.
A4 seen as a USB device.
Tried uninstalled and reinstalling.

Tried 3 different USB cables, hub, direct no hub, unplugging other USB devices.

Nothing seems to work

Any other ideas?
