MultiPort USB Hub and identical HID devices (pid vid)

[sswcharlie]

Where several HID rfid reader devices are used and they are all identical vid pid and no serial #, using VISA how do I prefix the port # to the rfid tag read before being passed to Excel ?  That is Excel will be able to differentiate between ports and list tags by ports.

The prefix, and how to, is the problem.

Thanks

Hi Charles,

What OS are you running? Prefixing the port number depends on the Operating System.

Additionally, I am a little confused why exactly you are trying to do this, would you be able to describe your application?

Thanks,
