# VT-Ragnaros: reconstructing Redragon SS552 USB control

> VT-Ragnaros implements a Linux driver and daemon for the Redragon SS552 Ragnaros USB control deck. It reconstructs commands and input reports from the vendor's SDLibrary1.dll, sending JPEG frames in 1024-byte USB packets and decoding key, knob, and touch-strip events for configurable profiles.
