Device or host role chosen at runtime

[SukkoPera]

I would like to make a device that:

• Starts up in device mode
• If it doesn't get connected to a host within 10 seconds, switches to host mode
• Otherwise it stays in device mode forever

Is this possible? I'm using a RP2040.

Yes, but it may encounter some not ready yet requirement. Let us know what you tried and what you achieve
