tetherscript/hvdk: Windows HID Virtual Driver Kit SDK · GitHub
The Tetherscript Virtual HID Driver Kit (HVDK) is a professional-grade Software Development Kit (SDK) designed for Windows to emulate human interface devices like keyboards, mice, and joysticks via software.
While it was once a go-to for developers and high-end gamers, the landscape for this tool has changed significantly. Below is a deep look into its purpose, its current status, and why it remains a unique piece of tech. What is the Tetherscript HVDK?
At its core, the kit allows software to "pretend" it is a piece of hardware. When you use it, the Windows operating system believes a physical USB keyboard or joystick has been plugged in, even though the signals are coming entirely from code.
Capabilities: It supports virtual keyboards, absolute/relative mice, and joysticks with up to 8 axes and 128 buttons.
Target Audience: It is primarily built for developers using C#, Delphi, or C++ who need to automate complex inputs or create custom controllers.
The "Secret" Driver: The drivers used in the HVDK are the same ones powering ControlMyJoystick, a popular tool for complex game controller remapping. The 2022 Discontinuance
As of December 5, 2022, Tetherscript officially discontinued the HVDK as a standalone commercial product. This move was driven by two major hurdles:
Windows Security: Microsoft has increasingly locked down driver configuration in Windows 11 and 11S.
Cost of Certification: Obtaining the necessary digital certificates to "sign" drivers so they are trusted by Windows has become prohibitively expensive for niche tools. How to Access it Now
Despite being discontinued, the kit isn't entirely gone. The community has found a few "backdoor" ways to keep using it:
ControlMyJoystick Trial: You can still get the signed, working drivers by downloading the ControlMyJoystick 14-day trial. The drivers typically remain on your system and continue to work even after the trial ends. Virtual HID Device Creation: The TetherScript Virtual HID
Open Source SDK: Tetherscript moved the SDK examples to GitHub, allowing developers to build their own routines on top of existing drivers.
Unofficial Wrappers: Unofficial projects like ghosteedd/hvdk have emerged, providing Python modules and C++ libraries to make these drivers easier to use for modern projects. Why it is Considered the "Best"
Among virtual HID solutions, Tetherscript is often cited as the best because its drivers are digitally signed. Most "fake" drivers require you to put Windows into "Test Mode," which breaks many anti-cheat systems in games and lowers system security. Tetherscript’s drivers are recognized as "real" by the OS, making them far more stable and compatible.
