DSU / Cemuhook motion server for the Steam Controller 2026 on Linux — works on Steam Deck, Bazzite, and any generic Linux desktop.
Inspired by SteamDeckGyroDSU by kmicki.
- Streams 6DoF gyro + accelerometer data over the DSU (Cemuhook) protocol
- Supports up to 4 Steam Controllers simultaneously (slots 0–3)
- Works via Bluetooth, USB-C, and the Proteus Puck wireless dongle
- Runs alongside SteamDeckGyroDSU — use both at the same time on Steam Deck
- Automatic gyro bias calibration (activates when the controller is held still for ~2 s)
- Runs as a systemd user service — starts automatically at login
- Compatible with Eden, Ryujinx, Cemu, and any Cemuhook-compatible emulator
sc2gyrodsu-config is a graphical tool bundled with the installation.
Remap raw sensor axes if your controller's gyro axes are swapped or inverted. Use the Auto-detect Axis Mapping wizard to detect the correct mapping automatically by following a short set of guided gestures.
Step-by-step guided detection. Read each instruction, position the controller, then press Begin ↵ or tap any button on the controller to start each 5-second capture window.
Live Attitude Direction Indicator (ADI) shows controller orientation in real time. Use it to verify your axis mapping is correct after running the wizard.
- Sky (blue) fills the display when the controller is face-up
- The horizon tilts and shifts as you roll and pitch
- The orange arc around the outside shows accumulated yaw
- Numeric R / P / Y readout at the bottom
Run a manual gyro bias calibration. Hold the controller still for the duration of the capture to zero out sensor drift.
Download the installer shortcut and double-click it on your Desktop:
The installer will:
- Copy the daemon and GUI tool to
~/SteamControllerGyroDSU/ - Install and enable the systemd user service
- Install udev rules (so the controller is accessible without root)
- Create Desktop shortcuts for the config tool, updater, and uninstaller
- Install the application icon

bash /tmp/SteamControllerGyroDSUSetup/install.shPoint your emulator's DSU / Cemuhook motion source at:
| Setting | Value |
|---|---|
| IP | 127.0.0.1 |
| Port | 26761 |
| Slot | 0 = first controller, 1 = second, … |
Settings → Controls → Motion → DSU Server → 127.0.0.1:26761
Settings → GamePad Motion Source → DSU1 → 127.0.0.1:26761
Run SteamDeckGyroDSU on the default
port 26760 for the Steam Deck's built-in gyro, and this service on 26761 for your
Steam Controller. Add both servers in your emulator:
| Port | Source |
|---|---|
26760 |
Steam Deck built-in gyro (SteamDeckGyroDSU) |
26761 |
Steam Controller 2026 (this service) |
- Run the Axis Wizard after installing — it detects the correct sensor axis mapping for your controller in under a minute.
- Run Calibration after the wizard — the axis remap invalidates any stored bias, so a fresh calibration eliminates gyro drift.
- Reset Yaw in the Test tab if the yaw reading has drifted (there is no magnetometer, so yaw integrates over time).
