Mac USB: MIDI Studio or Cubase don't see the One USB - malformed?

[jdmoog]

My Mac (Mojave 10.14.6) sees the One in the System Report, but it does not appear in the Audio MIDI Setup utility as all my other USB-equipped synths do, nor is it seen by Cubase 10.5 in Studio Setup. By using the Apple Developer utility "USB Prober" it looks to me like the One is not reporting the Interface properly - see below, "Interface #0 - Unknown"

By comparison, here's what the OB-6 shows, and it's similar with the ARP Odyssey, Prophet 6 & 12, Arturia MicroFreak, ...

And yes, the One is configured to use the USB in Settings MIDI I/O for both input and output. The One is plugged into the same MIDI hub as the others - a Belkin USB 2.0 hub (MTT).

I had the same problem. Some USB HUbs are not compatible or too much Hubs in series ore USB cable too long .
Try different Hubs or activ USB cable. I solved my Problem by using an activ USB cable (Mine was too long)
