We have 2 EVAL-ADUSB2Z adapters.
One came with the ADAU1442 eval board, the other one with ADAU1701 board.
we debug the board with the adau1442 processor in two locations.
and it seems that an adapter which came with the 1701 board doesn't want to work with the 1442 project.
It behaves fine when connected to the 1701 project, and shows usb communication failures when connected to the 1442 project
(even if not connected to the hardware).
Do the adapters for different eval boards have different firmware even if they have the same part number ?
