Hey ya'll. Was hoping for a quick phone call with tech support but in the spirit of the company, I've created a forum username and am posting my request for a replacement AD2. I run a pair of AD2s regularly and have them both powered by their own 5V auxiliary DC power supplies. To my dismay, I started receiving errors by my mac about USB over current. Turns out one of my AD2s stopped recognizing the AUX supply and started pulling current from the USB bus per the monitoring via Waveforms. After swapping the power supplies, it became clear that the power supplies are both fully operational. To be sure, I tested the voltages of the PSUs with my oscilloscope - no issues. The non-symptomatic AD2 works with each of them, confirming the connected AUX voltage in Waveforms with both PSUs. Troubleshooting again with no loads, ie. powering the AD2 units with the I/O connectors detached, replicates the issue. Please advise on how to further troubleshoot or obtain a replacement. I've come to rely heavily on these AD2s for my dev workflow and need to be up and running ASAP. Thanks ya'll.
