Powerology AM8268N: reconstructing a USB display protocol for Linux

Powerology AM8268N reconstructs the USB display protocol used by dual-screen laptop extenders built around the Actions Micro AM8268N. A Linux userspace driver presents each panel through evdi and sends JSON-RPC control and H.264 video over vendor-defined HID interfaces; the protocol notes derive from captures of the Windows application.
