WebHID Device Test
Use WebHID only when a standard keyboard, mouse, or gamepad API does not expose the specialized device you need to test.

Advanced hardware access
This advanced test only works in browsers that expose the required hardware API.
DeviceOK requests access only after you click. Advanced browser hardware APIs are permission-gated and are not universally supported.
Private by design
Device access is permission-gated and starts only after you choose a device.
Use the result as evidence, not a guess.
This test checks
- WebHID support
- Device selection
- Vendor/product identifiers
How to read it
Selecting a device proves the browser can request WebHID access to it.
It does not automatically prove every vendor-specific feature works.
