Redragon ships the SS-550 Stream Deck with Windows-only software. I use Linux, so I captured the USB traffic from the proprietary driver, decoded the protocol, and reimplemented it in userspace.



The result is an open-source Rust workspace with a background daemon plus an optional Tauri/GTK control panel. It builds from source on any Linux distribution and works on both Wayland and X11.



What it supports:



• 15 configurable keys across multiple pages, custom icons and brightness control

• Commands, URLs, typed text, hotkeys and chained multi-actions

• Live key widgets for clock, CPU, RAM, temperature, timers, weather and playerctl

• Per-application profiles that switch with the focused window

• OBS Studio WebSocket 5.x controls and live status

• Twitch viewer/follower counts, clips and chat actions

• A daemon-only mode for headless systems



Two details that may help anyone working with similar USB hardware:



• The udev rule uses TAG+="uaccess" instead of MODE="0666", and it must sort before 73-seat-late.rules — hence 60-redragon-streamdeck.rules.

• The device exposes multiple HID interfaces. Writes returned EPIPE until I selected the correct interface by usage\_page instead of assuming the first index.



Currently confirmed hardware: Redragon SS-550, USB ID 0200:1000. Other StreamDock/Mirabox-based devices may work, but I cannot test them yet.

If you own this device or a related model, I would appreciate test results. I am also happy to answer questions about the protocol, udev setup or architecture.



If you find the project useful, a GitHub star would help other Linux users discover it.
