We have updated our knowledge base article with the Mac Book Pro (Late Model 2016) with USB-C ports.

From that post:

We have identified a couple of compatibility issue where by the MacBook Pro (Late 2016) has an issue with correctly connecting to USB 1.1 and USB 3.0 audio devices not being seen by the bus correctly.

* The AudioBox USB is a USB 1.1 device and upon instantiating the interface in Sound Devices the AudioBox USB will drop off the USB bus. Further attempts to use different USB-C adapters or a USB-C to USB-B cable resulted in the same result.

** We have seen isolated incidents where the Studio 192 also has connectivity issues with the USB-C adapter.

In both cases both products work perfectly well with previously produced Mac systems.

Apple has been notified of these issues. They have not given any indication of when we can expect a fix.

The device drivers for our interfaces are provided by Apple. The Studio 192 uses UC Surface for control, yet just like the AudioBox USB the driver is provided by the Mac operating system.

We have determined that that putting a powered or un-powered USB hub between the AudioBox or Studio 192 and the computer resolves the connectivity issue. Our Tech Support group had been recommending using a Multi-TT hub, however that is not necessary as any USB 1.1, 2.0 or 3.0 Hub will work fine.

For these issues, we suggest contacting Apple about when they can provide an update so a Hub does not have to be used.

If you have already purchased the system and feel you have an issue not addressed in this update, please open a support ticket to let us know what your concerns may be.
