Device not detected
Symptoms: Wallet page shows "no device found" or device doesn't appear in Bridge.
Quick fixes:
- Check the USB cable — use an original/data-capable cable and try different ports.
- Unlock your device (enter PIN) before opening the wallet page.
- Restart Bridge (or the OS) and reload the browser.
- Temporarily disable other wallet apps/extensions that may monopolize USB access.
Permission/driver errors
Symptoms: OS prompts, permission denied, or driver errors on Windows/Linux.
- On Windows: run the installer as administrator and accept driver prompts.
- On Linux: check udev rules and ensure your user has USB device access; run sudo to install rules and log out/in after.
- On macOS: approve permissions under System Preferences > Security & Privacy if blocked.
Bridge update problems
Symptoms: Update fails, Bridge won't restart, or old version persists.
- Uninstall Bridge completely, reboot, then download and reinstall the latest version from an official source.
- Check for conflicts with security software (temporarily disable if safe to do so while updating).
- If firmware updates fail, ensure you have your recovery seed and do not interrupt power during the device update process.
