Device Tests

Choose a focused device test for microphone input, webcam preview, controller buttons, keyboard keys, mouse buttons, or input timing.

All tools run in the browser and are built for quick checks before calls, games, streams, recordings, or desk setup changes.

Which device test should I use?

Use the microphone test before recording or joining a call, the webcam test before streaming or meetings, and the gamepad tester before playing with a controller. Keyboard and mouse tests are useful after changing devices, layouts, switches, USB hubs, or browser settings.

Why does a device test need permission?

Browsers require explicit permission for microphone and camera access. If a test is blocked, check the browser prompt, operating system privacy settings, and whether another app is already using the device.

Camera and microphone blocked checklist

If camera or mic access is blocked, open the browser site settings for quicktesthub.com, allow the camera or microphone, reload the page, and check macOS or Windows privacy settings. Close Zoom, Meet, Teams, recording software, or other apps that may already be using the same device.

How to troubleshoot a failed device test

Start with the browser permission icon near the address bar, then check operating system privacy settings, input/output device selection, and whether another app is already using the same hardware. For USB devices, reconnect the cable or try a different port before assuming the hardware is broken.

Browser tests vs installed diagnostic apps

Browser device tests are best for quick confirmation that a website can receive your microphone, camera, keyboard, mouse, or controller input. Installed diagnostic apps may expose deeper driver details, but they are slower to set up. Use this hub first when you need a fast answer before a meeting, stream, game, recording, or support call.

Device Tests FAQ

Are these tests private?

The tests run locally in your browser. Microphone and camera pages request permission only so the browser can preview input on the page.

Why does my device work in one browser but not another?

Browser permissions, hardware API support, extensions, and operating system privacy settings can differ. Try Chrome or Edge when testing gamepads or media devices.

What should I test before a call or stream?

Run the microphone test, webcam test, and keyboard or mouse test if you recently changed devices, hubs, cables, drivers, or privacy settings.
