I'm trying to resurrect a project using some EVAL-ADAU1701 eval kits from 2011. I have used them in the past with Ver 3.11 and everything was fine. I have loaded version 3.12 and 3.13 beta and the USBi driver loads and I can see the driver in Windows 7 but when I link compile download I get a communication failed in the lower right corner and a pop up message that says USB communication failure. I have 3 sets of the eval kits and none of them work. When I first plugged in the USB dongle I think it downloaded new firmware to the dongle. Did the hardware change and the old hardware is no longer supported? What is the best way to get this up and running? Go back to old version?
