Unique ID

[ollietb]

Hi there
I'm creating an Electron app with 4 NFC readers attached. I am wondering whether there is a way of getting a unique ID per reader, so that I can tell which read has come from which device, even if I unplug and re-plug them back into a different USB port? At the moment I can see that the only unique identifier is the "Interface 1", "Interface 2" on the reader object, but that will change if I change the USB ports.

have you ever found a solution to that problem?
where did you get the interface numbers from?

No we had to go with a different solution in the end

This is not really a good solution but nfc-pcsc does assign unique device name when attaching additional devices.

The names do get reassigned when reattaching the usb devices the devices so we need to find a better solution.
