Why Trust usbRecognized?
We are not another ad-heavy tool site that harvests your data. Here is exactly what makes usbRecognized a trustworthy hardware testing platform.
Zero Data Collection
Every test runs locally in your browser using standard Web APIs. Your keystrokes, camera feed, microphone audio, and USB device info never leave your computer. Open Developer Tools (F12) → Network tab and verify it yourself — you will see zero outgoing requests containing your testing data.
Real Diagnostic Value
Our tools do not just say "working" or "not working." Each test provides specific diagnostic data: NKRO counts, CPS measurements, pixel-level dead pixel detection, refresh rate timing, audio latency measurements, and USB device enumeration with VID/PID lookup. We help you understand what is wrong, not just that something is wrong.
Educational Depth
Every tool page includes detailed guides explaining what each metric means, what causes common hardware failures, and how to interpret your results. We link to authoritative sources including ISO standards, manufacturer documentation, and peer-reviewed research — not just marketing claims.
Accessible to Everyone
24-language support means hardware diagnostics are available to users worldwide, not just English speakers. No account, no payment, no app install. If you have a browser, you have a complete hardware testing toolkit.
Open and Verifiable
Our site is static-generated and client-side only. There is no backend processing your data because there is no backend. The JavaScript running your tests is the same code you can inspect in your browser — nothing is hidden behind a server.

Frequently Asked Questions
What is Quick Device Check?
Quick Device Check is our flagship feature — a one-click hardware diagnostic that scans your keyboard, mouse, touch support, webcam, microphone, screen resolution, refresh rate, battery, and browser capabilities. It generates a Hardware Health Report with a score and recommends specific tools for any issues found.
Do I need to install anything?
No. usbRecognized runs entirely in your browser using standard Web APIs. There is nothing to download or install. As long as you use a modern browser (Chrome, Edge, Firefox, Safari, Opera), all basic tests work out of the box. Some advanced features like WebUSB scanning require Chrome or Edge.
Are these hardware testing tools really free?
Yes, all tools on usbRecognized are completely free. No registration, no download, no hidden fees. Simply open the tool page and start testing. We support the site through unobtrusive advertising — no paywalls, no premium tiers.
Is my data uploaded anywhere?
No. All tests run locally in your browser. Your keystrokes, camera feed, microphone input, and USB device information never leave your computer. We do not upload, store, or transmit any testing data to any server. You can verify this by checking your browser's network tab.
Which browsers are supported?
All modern browsers are supported: Chrome, Edge, Firefox, Safari, and Opera. For basic tests (keyboard, mouse, display), any browser works. For advanced features like WebUSB device scanning and WebHID, Chrome or Edge is required. We recommend Chrome or Edge for the full experience.
Does this work on mobile devices?
Yes, most tests work on mobile browsers. Keyboard testing works with on-screen keyboards and Bluetooth keyboards. Touch testing is specifically designed for mobile devices. However, some advanced features like WebUSB and WebHID require desktop Chrome or Edge.
Can I test my keyboard online?
Yes. Open our Keyboard Tester and press any key — it will light up on a visual keyboard layout. You can also test NKRO (N-key rollover), detect ghosting, check for chattering switches, and measure key press latency. It works with mechanical, membrane, laptop, and Bluetooth keyboards. No download required.
Can I test my mouse online?
Yes. Run the Quick Device Check for a fast overview of your mouse status, or use the dedicated Mouse Test tool to verify every button (left, right, middle, side buttons), measure CPS (clicks per second), test double-click detection, and check scroll wheel functionality. All testing happens in your browser.
Can I test my webcam and microphone?
Yes. The Quick Device Check can instantly verify that your webcam and microphone are detected and working. For a more detailed test, use the dedicated Webcam Test and Microphone Test tools — you can preview your camera feed, check resolution and frame rate, and test microphone input levels. Just grant browser permission when prompted.
Why isn't my USB device detected?
USB device detection requires WebUSB API, which is only available in Chrome and Edge. Make sure you're using one of these browsers. Also, some USB devices require specific drivers or permissions. Try clicking the "Connect" button and selecting your device from the browser's USB device picker.
How do I know my data is safe?
All tests run entirely in your browser — there is no backend server processing your data because the site is statically generated. Your keystrokes, camera feed, microphone audio, and USB device information never leave your computer. You can verify this yourself: open Developer Tools (F12), go to the Network tab, and run any test. You will see no outgoing requests containing your testing data. The only external requests are for Google Analytics (anonymous page view statistics) and ad serving.
What should I do if a hardware test fails?
Each tool page includes a detailed diagnostic guide that explains common failure causes and solutions. For example, if your keyboard test shows chattering (double registrations), the guide explains whether to clean the switch, replace it, or adjust firmware debounce. If your webcam test shows low resolution, the guide walks you through checking browser permissions, driver settings, and bandwidth limitations. Scroll to the FAQ and diagnostic sections on each tool page for specific troubleshooting steps.
