Connection help
If your controller is not detected, hold the Plus (BOOT) button, tap RESET, then release Plus. Reconnect and try again. Do not unplug the controller while it is being erased or written.
The installer sends a one-way identifier derived from the controller's factory MAC address. The raw MAC is not sent. Registration is an access allow-list, not cryptographic proof of ownership.
