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.
