I just purchased a new analog discovery 2 and switched power supply from Digilent . The Analog Discovery 2 works fine when powered by the USB cable from the computer but it does not work at all when the Analog Discovery is powered by the Digilent switched power supply. The software shows no device detected. The switched power supply shows 5.1 Volts. So the problem appears to be with the Analog Discovery 2 auxiliary power supply input. Do I have a defective Analog Discovery 2 or am I missing something. How do I get a warranty replacement?
