Turn Raspberry Pi Pico W into a Driverless USB WiFi Adapter

Pico W firmware creates driverless USB WiFi bridge (Layer-2)

Turn Raspberry Pi Pico W into a Driverless USB WiFi Adapter

I discovered an open-source firmware that transforms the Raspberry Pi Pico W into a driverless USB WiFi adapter. This solution creates a transparent Layer-2 bridge, allowing Windows, Linux, and macOS to connect without installing specific drivers. While limited by the USB 1.1 interface to about 4.75 Mbits/sec, it serves as a perfect emergency connectivity tool using spare hardware.

It's mostly useful for an emergency when you need WiFi connectivity and have a spare Raspberry Pi Pico W lying around.

    I was trying to do a virtual camera on the RP Pico but found the LLMs to be really bad at it. So impressive work.
