Fix common USB recognition and connection issues.
USB issues may stem from the cable, device, power or Windows driver.
- Try another port: Connect directly to a different working USB port.
- Test the device elsewhere: Check the same device on another PC, using another cable when relevant.
- Inspect Device Manager: Look for warning icons under USB controllers and the device category.
- Avoid unknown drivers: Use Windows Update or the device manufacturer’s official driver.
How to use this tool
Follow the steps above. Browser tests run locally when possible; other tasks provide practical troubleshooting guidance rather than claiming to scan your computer or network.
