Trezor Bridge Not Working? Fix It Fast


If your computer or browser can’t detect your Trezor device, it’s often due to Trezor Bridge not running properly or connectivity issues. Follow these steps to resolve the problem:

1. Restart Your Computer and Device

  • Disconnect your Trezor device.
  • Restart your computer.
  • Reconnect your Trezor after the reboot.
  • Open your browser and try connecting again.

2. Check If Trezor Bridge Is Running

  • Windows: Look for the Trezor Bridge icon in the system tray (bottom right).
  • macOS: Check the menu bar at the top.
  • Linux: Use system monitor or terminal to check if the trezor-bridge process is running.

If it’s not running, manually start it or reinstall Bridge.

3. Reinstall Trezor Bridge

  • Uninstall the current Trezor Bridge version.
  • Download the latest version from trezor.io/bridge.
  • Install it fresh and restart your computer.

4. Use a Different USB Port or Cable

  • Try plugging your Trezor into a different USB port.
  • Use the original USB cable or a high-quality replacement.
  • Avoid USB hubs; connect directly to your computer.

5. Update Your Browser

  • Make sure your browser is updated to the latest version.
  • Supported browsers include Chrome, Firefox, and Edge.
  • Clear browser cache and restart the browser.

6. Disable Conflicting Browser Extensions

  • Some browser extensions may block USB access.
  • Temporarily disable extensions and try reconnecting.
  • Especially check for security or privacy-related extensions.

7. Check for Firmware Updates on Your Device

  • Use Trezor Suite or Trezor.io/Start to update your device firmware.
  • Outdated firmware can cause communication issues.

8. Verify Computer Permissions

  • Ensure your computer allows USB device access.
  • On Windows, check Device Manager for Trezor device status.
  • On macOS, review System Preferences > Security & Privacy.

9. Try an Alternative Setup

  • If problems persist, try using the Trezor Suite desktop app instead of the browser.
  • The desktop app does not require Bridge and often bypasses connection issues.
