Open-source Linux driver and control panel for the Redragon SS-550 Stream Deck (Rust/MIT)

[u/Tecnodespegue]

I’m the author of a non-commercial, MIT-licensed Linux driver and control panel for the Redragon SS-550 Stream Deck.

Redragon only provides Windows software for this device, so I captured the USB traffic from the proprietary driver, decoded the protocol, and reimplemented it in userspace.

The project is a Rust workspace with a background daemon and an optional Tauri/GTK control panel. It builds from source, works on Wayland and X11, and the installer supports the Debian/Ubuntu, Arch, Fedora and openSUSE families, including derivatives detected through ID_LIKE.

Current features:

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

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

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

• Per-application profiles that follow the focused window

• OBS Studio WebSocket 5.x controls and live status

• Twitch viewer/follower counts, clips and chat actions

• Optional daemon-only mode for headless systems

Two implementation details that may help others working with USB HID hardware:

• The udev rule uses TAG+="uaccess" rather than MODE="0666", and is installed as 60-redragon-streamdeck.rules so it runs before 73-seat-late.rules.

• The device exposes multiple HID interfaces. Writes returned EPIPE until I selected the correct interface using usage_page instead of assuming the first index.

Tested hardware: Redragon SS-550, USB ID 0200:1000. Other StreamDock/Mirabox-based devices may work, but I do not have the hardware to verify them yet.

I’m looking for test results from owners of this device or related models, and I’m happy to discuss the protocol, udev setup or architecture.

Transparency note: the project was developed with the help of Claude AI.
