tetherscript/hvdk: Windows HID Virtual Driver Kit SDK - GitHub
Tetherscript has published the SDK, including C# and Delphi example code, on their HVDK GitHub repository Technical Specifications Supported Systems: Designed for 64-bit versions of Windows 7, 8, 8.1, and 10. Incompatibility: These drivers do work on 32-bit Windows operating systems. Functionality:
Tetherscript is frequently cited as the "best" choice for complex input manipulation due to several distinct technical advantages: 1. High-Performance Architecture
This comprehensive guide explores why this toolkit is considered the best in its class, its core features, practical applications, and how it compares to alternative solutions. What is the Tetherscript Virtual HID Driver Kit?
Users have reported issues where the virtual drivers are detected as active controllers in games (e.g., Steam games on Steam Deck), sometimes blocking physical controller input until the Tetherscript drivers are disabled or uninstalled. Modern Alternatives tetherscript virtual hid driver kit best
Despite its discontinuation, the HVDK left a legacy, having been used in several notable projects.

tetherscript/hvdk: Windows HID Virtual Driver Kit SDK - GitHub
The is a software development kit (SDK) designed for Windows that allows developers to emulate hardware-level input devices like keyboards, mice, and gamepads. Although the kit was officially discontinued in December 2022, its drivers remain widely used for legacy support and hobbyist automation projects. Key Features and Capabilities tetherscript/hvdk: Windows HID Virtual Driver Kit SDK -
Future research directions for the TetherScript Virtual HID Driver Kit include:
Supports both absolute and relative positioning.
To appreciate Tetherscript’s offering, one must first understand the limitation of user-mode input simulation. Standard Windows input injection functions generate messages that travel through the USER32 subsystem. Consequently, anti-cheat engines in video games, secure input fields (password managers), and remote desktop protocols can easily distinguish synthetic input from physical hardware events. They look for the absence of hardware interrupt requests (IRQs) or signature flags within input structures.
: Uses the same underlying drivers as Tetherscript’s ControlMyJoystick software, a popular tool for converting non-standard inputs (like voice or phone sensors) into gaming commands. Current Availability and Support Status If you are a developer
Often used by gamers (especially Steam Deck users) as a modern alternative for controller emulation.
If you are a developer, I can help you find the for the C# or Delphi examples. If you are a gamer,
HVDK bypasses this barrier by deploying a kernel-level driver that maps directly to the Windows HID class architecture. When your software sends data to the Tetherscript driver, the OS interprets it as raw hardware telemetry coming from a physical USB device port.
You can still obtain the Tetherscript-signed drivers by downloading the ControlMyJoystick 14-day free trial . The drivers remain functional even after the trial ends. Open Source:
