The serial number packets had no checksumming or crypto, making the proxy straightforward. Replacement rollers were cheap and readily available, restoring full functionality. Why: If you ship connected hardware that phones home for activation, this shows how trivially a USB man-in-the-middle can defeat server-side lockout when the device protocol lacks signing or checksums. Founders and engineers building IoT or cloud-locked devices should treat this as a concrete lesson: any device-level identity sent over USB without cryptographic integrity can be spoofed with a $1 microcontroller. hardware-hacking reverse-engineering usb right-to-repair security
