Topic: Babyface Pro not recognized via USB-C hub following High Sierra update

After updating my 2016 MacBook Pro to High Sierra, my Babyface Pro is no longer recognized when connected via a AUKEY USB-C / USB 3.0 hub supporting Power Delivery.

Symptoms are:

  • no audio device in System Preferences > Sound

  • Fireface USB Settings.app won't start

  • Totalmix.app can't see any connected device

However, the Babyface Pro *is* recognized as normal when connected using Apple's own USB-C to USB-A adaptor, and also when connected via a Wavlink 7-port USB-C / USB 3.0 hub which does not support Power Delivery.

Furthermore, in the AUKEY hub, other USB audio devices (besides the Babyface Pro) *are* recognized.

So for the time being, I have the Babyface Pro connected on the Wavlink 7-port hub.

However this is not ideal, as it is now sharing bandwidth with a lot of other devices. The reason I had it on the AUKEY hub is that there are NO other attached USB devices, just Power Delivery for charging the laptop - so the Babyface Pro had all the data bandwidth to itself.

Any ideas why this could be? Is there a particular thing to look out for when determining whether a USB hub will work or not?

Re: Babyface Pro not recognized via USB-C hub following High Sierra update

Apple just released macOS 10.13.2, and since the release notes say "Improves compatibility with certain third-party USB audio devices", I thought I'd install the update and re-test this issue.

The result is, I can no longer reproduce the issue. The Babyface Pro once again works when connected via the AUKEY USB-C / USB 3.0 hub supporting Power Delivery, so the issue appears to be "fixed".

Thanks for reporting. It's good to hear that Apple's fixes fix problems for some.

Well, I'm not really sure if this was fixed by macOS 10.13.2 or something else.

And sadly, a more serious USB audio issue has not been fixed in macOS 10.13.2 - ISSUE 2 in this post: https://www.forum.rme-audio.de/viewtopic.php?id=24842
