Judgement

What it is

Developer tool

What it does

Captures the USB traffic between a gadget and its maker's app, works out the protocol with evidence, and generates an open Python driver; also runs as an MCP server for AI agents.

Adopt it when

You have a USB device that only works with a vendor's app and want an open driver for it, typically on Linux.

Watch out

A young project from one maker; capturing traffic needs the vendor's app running and Linux usbmon or Wireshark.
