WebHID (Human Interface Device)

Category: Device
Type: New or changed feature
Status: Enabled by default (Chrome 89)
Intent stage: Shipped

Summary

Enables web applications to interact with human interface devices (HIDs) other than the standard supported devices (mice, keyboards, touchscreens, and gamepads). However, there are many other HID devices that are currently inaccessible to the web. This API allows web applications to request access to these devices, send and receive HID reports, and retrieve information about the report descriptor.
