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

pico-usb-wifi is an open-source firmware project that converts the Raspberry Pi Pico W into a driverless USB WiFi adapter that works with Windows, Linux, macOS, and other operating systems with USB CDC-NCM support. The Infineon CYW43439 chip found in the SBC can’t be used directly as a USB to WiFi bridge, and instead, the firmware implements a transparent Layer-2 bridge between the Pico W’s wireless module and USB interfaces.
