I have seen a few older posts on this, but nothing recent. Does CDC work with Linux, or is there something special that needs to be done?
My situation, I have CDC working fine between the FEZBit and Windows, but when I plug the FEZBit into my RPI it fails to register the port. Here are my dmesg logs:
