WebUSB and RFID readers
I was wondering if anyone has any experience of getting RFID readers to work over WebUSB. The reader I'm using is https://www.parallax.com/product/28340 .
From what I've read, I would have to write a driver to read from the device. I just wondered if anyone did any work in this regard and what they did.
The goal here is to read RFID tags without using another application to submit it to the web application.
Thank!

The USB version of this RFID reader uses the FTDI FT232R chip to provide a USB serial interface. If the host operating system has a driver for this chip, or the FTDI virtual COM port drivers are installed, the browser will not be able to connect to the device when your application requests it via the WebUSB API, because the USB interface presented by the device will already be in demand by the driver.
If you can ensure that the virtual COM port driver is not loaded, you can write the driver using the WebUSB API to control the device.
