Trezor Bridge | Secure Connection Between Wallet & Browser

Introduction

Trezor Bridge is generally reliable, but users may encounter occasional connection problems. This guide breaks down the most common issues and how to resolve them quickly.

Device Not Detected

One of the most frequent issues is the device not appearing in Trezor Suite. To fix:

  • Check the USB cable and port.
  • Try a different cable capable of data transfer.
  • Restart Trezor Bridge or your computer.

Outdated Bridge Version

Running an outdated version can lead to compatibility issues. Always download the latest release from the official Trezor website. Updates resolve bugs and provide better device support.

Conflicts with Other Applications

Some applications—especially those that monitor USB devices—can interfere with Bridge. Close programs like antivirus USB monitors, Android File Transfer, or virtual machine tools that may take control of USB communication.

Browser Problems

If you’re using a browser-based interface:

  • Clear cache
  • Restart your browser
  • Ensure WebUSB permissions are correctly set

For Trezor Suite desktop, browser issues usually do not apply, making Bridge more reliable.

Reinstalling Trezor Bridge

If all else fails, uninstall Bridge completely and reinstall it. This resets background services and resolves corrupted installation files.

Operating System Issues

Some OS updates temporarily break USB communication. Restarting your computer or applying the latest patches often resolves these issues.

Conclusion

Most Trezor Bridge problems are easily fixable with simple steps such as updating software, checking cables, or restarting services. With proper troubleshooting, users can restore full device functionality and continue managing their crypto securely.
