webusb - USB device interface has been blocked

Question

I am trying to use USB RFID reader in our website. by using navigator.usb.getDevices() i am selecting my device.

open() and selectConfiguration(1) is working. but device.claimInterface(0); is giving me following error.

An attempt to claim a USB device interface has been blocked because it implements a protected interface class.

Answer 1

Chrome prevents certain interfaces from being accessed for security reasons. These interfaces are the following:

• audio
• HID
• mass storage
• smart card
• video
• audio/video
• wireless controller

These are detailed in the following Chrome web test: https://cs.chromium.org/chromium/src/third_party/blink/web_tests/usb/protected-interface-classes.html?q=usb+protected+interface&sq=package:chromium&dr=C&l=9

There is a proposal for WebHID in progress, however: https://discourse.wicg.io/t/human-interface-device-hid-api/3070
