I was expecting the two CODE amps to work together on USB, so I can get 2 guitar traces into my Mac in parallel. Unfortunately I'm disappointed to see that Mac will only see ONE CODE at a time. Looks like they both have the same device ID which creates issue on the bus?

Is this an actual bug? If so, please remove this limitation via firmware update because it would definitely make sense to have more than one CODE connected to the computer without needing additional hardware such a sound interface.
