pico-usb-wifi is firmware for the Raspberry Pi Pico W that turns it into a driverless USB Wi-Fi adapter, enumerating as a USB CDC-NCM device.

Love the way the author labels each of his diagrams as “AI Slop”!

Can you have the Pico operate as an access point? Would love to be able to use this to connect over wifi to a printer (printer in client mode), with the printer and macos talking directly over IP without needing to configure any other routing/forwarding on macos.

> I spent two days of a long holiday weekend and about one million Claude Code tokens building this firmware.

Google Gemini is that naysayer senior developer who confidently tells you it can’t be done.

Claude is that easy to get along with smart hard working guy who just gets on with it and builds it double quick.

ChatGPT is the eager senior developer who says it can be done but can’t actually work it out and fluffs it.

Interesting that Gemini said it was infeasible. It should be aware that using a Pico W as a transparent ethernet bridge has been done several times over in open source projects, for example on BlueSCSI (emulating a Daynaport SCSI-Ethernet adapter) and PicoMEM and my own PicoGUS project (emulating an NE2000 Ethernet adapter).

You can do this by installing OpenWRT on the Pi and controlling it from the web interface.
