I believe the device also needs to be WebUSB compatible, unless that part of the design changed - it's a measure to reduce the attack surface by not letting webpages talk to old pre-WebUSB hardware that might have vulnerabilities.
- TobTobXX 4y agoIf I'be read it correctly it _can_ announce itself over WebUSB. And I suppose this announcement contains a landing URL, which Chrome will then show upon plug-in of the device. So device-side WebUSB capability seems like a feature, rather than a requirement for browser-side communication.
- selfhoster11 4y agoIt’s certainly not a requirement for the device to support WebUSB. NetMD recorders were created long before WebUSB, but can still be used from a browser app.
