USB Sound assertion in AppleUSBAudioDevice with return 0xE000404F at line 3834

My MacBook Pro is running 10.10.1. My company is building a USB audio device. When I plug that device into a USB port on my Mac, I see this message appear in the console log:


1/27/15 3:58:59.000 PM kernel[0]: USB Sound assertion in AppleUSBAudioDevice with return 0xE000404F at line 3834


Can someone please explain what this assertion means?


The device is a microphone, and it appears to be functioning properly.


Thanks.


-Matt
