Frequently Asked Questions
How do I view USB device information?
Click "Request USB Devices", select your USB device from the browser prompt, and grant permission. The tool will display detailed information including vendor ID, product ID, manufacturer, and device capabilities.
What browsers support WebUSB API?
WebUSB is supported in Chrome, Edge, and other Chromium-based browsers on desktop. Firefox and Safari do not support WebUSB. Mobile browsers generally do not support this API.
Why is my USB device not showing up?
Ensure: (1) you're using a Chromium-based browser, (2) the device is connected, (3) you've granted USB permission in browser settings, (4) the device is not already in use by another application.
Is it safe to grant USB access?
The tool only reads device information (vendor, product, serial) and does not modify or send data anywhere. Access is temporary and requires permission each time. No data is stored or transmitted to servers.
What devices can I inspect?
Most USB devices can be inspected: keyboards, mice, webcams, audio devices, storage drives, Arduino/development boards, and custom USB devices. Some devices may have restricted access for security reasons.
