trezor.io/start — Installation Notes

Browser vs Desktop App

Some Trezor workflows use a desktop helper (Bridge) or the official Suite app. Use the method recommended by the vendor for your OS.

Quick Diagnostics

• Device not found? Try a different USB cable (data-capable) or port.
• On Linux, ensure udev rules allow USB device access for your user.
• Restart the helper service or browser and reconnect the device.

Developer Tip

Check process list for bridge/daemon and allow browser permission prompts when using web-based flows.
