WebHID driver for Redragon King Ultra
King Ultra is the first Live mouse in UMD at umdrivers.com. The protocol comes from reverse-engineering the official Windows software — now you tune the mouse in Chrome/Edge like a modern web tool.
What you can configure
UMD mirrors the key OEM screens: buttons, sensor, settings, and macros.
- DPI and active stage
- Polling rate up to 8K (mode dependent)
- LOD, Peak Performance, ripple / angle / motion sync
- Debounce, sleep, long distance
- Import / export UMD JSON profiles
How to connect
Open https://umdrivers.com, click Open driver or the King Ultra card. In the WebHID prompt pick the vendor/dongle interface (not the plain “HID-compliant mouse”).
FAQ
What VID:PID does King Ultra use?
UMD whitelist: 3554:F54D, 3554:F54F, 3554:F510 (wired / dongle).
What is UMD?
Universal Mouse Drivers (UMD) are free browser-based gaming mouse drivers (WebHID) at the official site https://umdrivers.com. Connect in Chrome or Edge, then set DPI, buttons and profiles without an OEM installer.
What is the official UMD domain?
The official domain is https://umdrivers.com (Universal Mouse Drivers). The legacy host mouse.vxh.pl may redirect to umdrivers.com.
Which mice are supported?
Live: Redragon King Ultra and Rampage Blitz Ultimate. WIP: G-Wolves Fenrir Max 8K and Logitech PRO X SUPERLIGHT (gen1). The list grows as more protocols are reverse-engineered.
Do I need a Windows install?
Mouse configuration only needs Chrome or Edge on https://umdrivers.com. The optional UMD Battery Tray (Windows .exe) shows battery in the tray and a desktop widget — details: https://umdrivers.com/tray.
Is UMD safe for my mouse?
We only talk to the whitelisted VID:PID for that mouse. Other HID devices are never opened. Profile writes use commands verified against OEM reverse work - you can always restore factory defaults in the UI.
Why not use the official driver?
Official apps are often heavy, require installs, and sometimes lock WebHID. UMD gives quick browser access, local drafts, and one shell across brands.
How do I get my mouse added?
Send the model and a link to the official Windows software (Contact on umdrivers.com) or open a Device request on GitHub. You can also loan hardware for testing via TikTok.
