we are trying to connect to your evaluation board, but when selecting the Evaluation Demo, it seems like everything is frozen and after maybe 10s we get a message "USB communication failed".
It's also strange that 4 buttons are considered pressed, when on the datasheet it's said that only one can be applied at a time.
Is there anything wrong with our copy of the Evaluation Board?
I have seen that other customers had the same issue: EVAL-AD7147EBZ "USB communication failed" problem - Q&A - Precision ADCs - EngineerZone (analog.com)
We have tried on 2 computers and we get the same problem.
