Browser-based tests for keyboards, mice, displays and USB
About usbRecognized
usbRecognized is a free website for checking computer hardware without installing anything. It is aimed at gamers, tech enthusiasts and anyone who wants to confirm that a keyboard, mouse, monitor, webcam, microphone or USB device is working properly. Each test opens right in the browser, so there is no download and no account to create.
The site covers input devices, displays, audio, cameras and USB connectivity. Tests report specific measurements rather than a simple pass or fail, such as key rollover counts, clicks per second, dead pixel detection, refresh rate timing and USB device identification. Detailed guides explain what each metric means and what commonly causes failures.
What sets it apart is its privacy stance. The site says every test runs locally using standard web APIs, with no uploads of keystrokes, camera feed or audio, and it is available in 24 languages.
