WebUSB API browser support

Published 2026-09-022026-09-02By Carey Gill · Editorial process

The WebUSB API lets a web app request access to a non-standard USB device through navigator.usb.requestDevice(), filtered by vendor and product ID, and communicate with it directly after open(). The configuration and interface numbers to select and claim come from the device’s own descriptors in device.configurations; claimInterface() takes an interface for exclusive use until releaseInterface() or close(). The request needs a secure context and transient user activation.

The table covers navigator.usb.requestDevice() and the core device pairing flow, derived from MDN browser-compat-data.
