How I connected a GoPro Hero 13 to a laptop — and ended up patching KDE

▤ Summary

This article walks through debugging a GoPro HERO13 USB connection and tracing its MTP behavior. It shows how the device exposes CDC Network and MTP interfaces and how the author inspected USB descriptors and traffic with Wireshark and usbmon. The core outcome is a Lua dissector for Wireshark 4.2.2 that can parse MTP over USB packets while ignoring unrelated CDC Network traffic. The article also connects the technical work to KDE’s kiod MTP handling and notes a patch to improve device update behavior when storage events arrive. The final result is a software-side fix and protocol tool improvement for Linux desktop file transfer workflows.
