I am working with the 2013.4 ADV7511 reference design for the Zynq Mini-ITX board, and I'm running the Ubuntu desktop. Everything works fine, except that usb and adau1761 audio are mutually exclusive. If I add the usb information to the dtsi file, the audio codec stops working (but I have a mouse and keyboard). If I leave the usb entry out, the adau1761 works fine, but of course there is no usb recognized. I am confounded trying to understand the possible connection between the USB and the audio codec, and this issue is definitely repeatable 100% of the time. Any ideas on what could be going on would be appreciated. Thanks.
