Troubleshooting Common Trezor Bridge Issues

Even with smooth initial setup, users may occasionally hit snags with Trezor Bridge. Below are the most frequent problems and their solutions.

1. Device Not Detected Symptoms: Bridge icon is gray; browser shows “No Trezor device found.”

USB Cable/Port: Test a different cable or switch between USB-C and USB-A ports.

Permissions (Linux): Run sudo usermod -aG plugdev $USER then log out/in.

Reinstall Bridge: Uninstall via Add/Remove Programs (Windows) or Homebrew (macOS: brew uninstall trezor-bridge), then reinstall the latest version.

2. Stuck at “Waiting for Trezor” Symptoms: Browser hangs at connection prompt.

Firewall/Antivirus: Temporarily disable to see if Bridge’s RPC port (21325) is blocked.

Manual Restart: Right-click Bridge icon → “Restart Bridge” → retry connection.

3. Firmware Update Fails Symptoms: Error message like “Failed to continue” during update.

Battery/Power: Ensure the device is plugged into a powered USB port, avoid hubs.

Use Trezor Suite: The desktop app often handles updates more robustly than web wallets.

4. Browser Compatibility Symptoms: Certain browsers (e.g., older Edge versions) won’t connect.

Recommended: Chrome (v80+), Firefox (v75+), Brave, or Opera.

Disable Extensions: Privacy/ad-block extensions can interfere—whitelist Bridge.

5. Multiple Devices Confusion Symptoms: Connecting two Trezor units yields mixed responses.

Explicit Selection: In the connection dialog, select which serial number matches your intended device.

One at a Time: Disconnect extra units when performing critical operations.

By methodically isolating USB, software, and browser factors, you can resolve 95% of Bridge-related hiccups quickly, ensuring uninterrupted access to your crypto.
