New tool makes reverse-engineering USB devices way easier

A new open-source tool called usb-rea helps hackers decode secret USB protocols from proprietary devices. It works by capturing USB traffic while you use a device with its official software, then automatically generates reports, driver code, and Wireshark dissectors from the recorded data.

For tinkerers frustrated by abandoned peripherals or closed-source hardware, this tool dramatically cuts down the tedious work of reverse engineering. While you still need the original vendor software for initial recording, usb-rea creates reusable documentation that could keep devices working long after manufacturers stop supporting them. This represents a practical step toward hardware freedom in a world of proprietary controllers.
