This sounds like you're requesting development assistance more than reporting a browser issue. A quick internet search reveals a StackOverflow thread about WebUSB and Smart Card readers: https://stackoverflow.com/questions/66420229/webusb-api-and-pc-sc-smart-card-readers

hi this is not helping me

I'm sorry if that thread is unhelpful, but I'm afraid this repository is not for development assistance. This repository is only about browser compatibility and bugs, and your browser is behaving as per the specification (see https://wicg.github.io/webusb/#dom-usbinterface-isprotectedclass-slot for reference). If you need development assistance, I highly recommend searching around or asking on StackOverflow, a dedicated help forum for coding.
