Type: Chromium catches up
Status: Enabled by default (Chrome 117)
Intent stage: None

Breaking change: No
Enterprise impact: None

Web Platform Tests: No

WPT details: No, because browser picker implementation is implemented outside of Blink and so isn’t testable fully by web-platform-tests.

Summary

The "exclusionFilters" option in navigator.usb.requestDevice() allows web developers to exclude some devices from the browser picker. It can be used to exclude devices that match a broader filter but are unsupported.
