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.

  • Is there a different version of OSX on the two computers? Also, just to eliminate the USB port, try plugging it into the other port if you have one. – dwightk Mar 20 '14 at 14:04
  • Both running os x 10.9.2. And yes i have tried both ports with different cables. – Paul Mar 20 '14 at 14:07

    Since they are on the same version I'd look to make sure there isn't some driver software you installed on the one that's working. It doesn't look like the product page has something, but who knows. – dwightk Mar 20 '14 at 14:10
  • The sound card does not need a driver. There isn't even one for it. Apps installed on both machines is almost identical... – Paul Mar 20 '14 at 14:12
  • I'm out of ideas. You might want to try copying and pasting the text from the console which will help people having a similar problem if we can solve it here. – dwightk Mar 20 '14 at 14:15

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.
