What this test checks

This page reports selected browser capabilities and media devices that web APIs are permitted to expose. It helps confirm whether camera, microphone, USB, Bluetooth, serial, or related interfaces are available to this browser.

How to interpret results

Supported means the browser implements an API, not that a physical port or device is healthy. Device lists may remain generic until permission is granted, and an unavailable result may reflect browser or security policy.

Limitations

A web page cannot inventory every physical connector, test voltage or data lines, or inspect devices hidden by the operating system. API support varies by browser, platform, secure context, and administrator policy.

Troubleshooting

Reconnect the device, grant the relevant permission, use HTTPS and a compatible browser, check operating-system detection, remove hubs or adapters, and test the same hardware in its normal application.
