Alright, so brand new purchase. Figured it would just be plug-n-play. El Capitan, everything works! I also have a Centrance Micport Pro USB Interface; and it works just fine. No issues what so ever.

Plug the Audiobox in /w the stock cable... Nothing, move it to the other USB port; and finally it shows up but only momentarily, then it starts to disappear and show up again a few times until it's gone for good.

Unable to make it work!?!?!? Any ideas.

There is a huge thread on the Apple forums about this, we are not the only vendor that this is a problem with.

We are using the Apple Class driver, while your other interface is using a custom device driver. It is the USB Device driver in Mac OS X that is failing.

We logged a bug with Apple about it before El Capitan came out and reports are coming through that 10.11.4 (now in beta) may finally fix this.
