With multiple rfid readers all the same vid pid and no id available, is it possible to add a suffix/prefix to the tag read into LibreCalc. Currently all tag reads go into the same column in LibreCalc. Would need to be a reference to the USB hub port that the reader currently passing data is on.
Which is the best way to achieve
Thanks
