Hi,

If I well understand your question: you would like to connect 2 CR95HF demonstration board through USB on the same PC and you would like to know whether this is supported by the CR95HF.dll library and in case this is supported, you would like to know how to identify the USB devices?

Please confirm our understanding of your question and feel free to share more details on your use case

​Hi,

I've discussed internally: the CR95HF.dll library and the PC software can only handle a single instance of the CR95HF demonstration board.
