sc2dsu is a small utility published by NightHammer1000 that functions as a Cemuhook DSU server designed for the 2026 Steam Controller, exposing the device's gyro, buttons, and axis inputs over the DSU (DualShock UDP) protocol. Its purpose is to bridge the controller's hardware inputs to applications and emulators that understand the Cemuhook motion-source protocol, allowing motion-controlled titles and input-remapping tools to consume gyroscopic data alongside conventional button and axis events as if they originated from a standard motion-capable gamepad. Typical use cases include feeding gyro aiming into emulators that implement Cemuhook support, supplying motion data to input-mapping software for steering, camera control, or pointer-style aiming, and consolidating the Steam Controller's combined button and axis state into a protocol that many PC gaming tools already accept without additional drivers. Within a software catalog, sc2dsu fits the game controller, input-device driver, and emulator compatibility categories, sitting alongside other DSU server implementations and motion-input middleware. The project is currently at version 0.2.0, and the catalog records only a single published version, indicating an early-stage release in the 0.x development line where the feature set and protocol handling may still evolve between updates. As a focused single-purpose tool, sc2dsu does not attempt to manage the controller's full configuration surface; instead, it concentrates on translating the 2026 Steam Controller's sensor and input stream into the widely supported Cemuhook DSU format, making the device usable in environments where native support for this specific controller revision is otherwise unavailable.
