Sound card (Audionengine D1) not working on new MacBook Pro Retina My soundcard (USB DLC Audioengine D1) is not working on my new MacBook. My old MacBook Air from 2012 has no problem with it.

When plugged in the device, I get this weird error in the Console. Looks like there is a problem with detecting the USB device.

As recommended for similar problems, I have already tried resetting my NVRAM/PRAM - http://support.apple.com/kb/ht1379 - but that hasn't changed anything.
Never got this working in the end, but instead I fixed it with a neat workaround. All MacBook Pros come with inbuilt optical out. Using a small adapter I could use that to digitally send the sound (just like USB) to the D1.
