TL;DR I would recommend AGAINST using pyusb for HID use cases, if you are on Linux instead use udev.
If you need to know the device that was used to read, I would create a virtual device id if you really want to read directly from pyusb.. BUT I would recommend against it. I've not had to deal with this as I only use one device per USB host. Take a look at: * https://github.com/clach04/keyboard2mqtt - recommended approach, NOTE doesn't have great user-facing documentation but the code should be easy to read * https://github.com/clach04/pyusb-keyboard-alike - hitting USB directly On Tue, May 7, 2024 at 2:44 AM Charles Harris <charl...@slingshot.co.nz> wrote: > Hi > > There are many USB rfid devices to read tags.
