Tetherscript Virtual Hid Driver Kit | RECENT |

In the world of software and hardware interaction, few challenges are as persistently frustrating as simulating a Human Interface Device (HID)—such as a keyboard, mouse, or joystick—from standard application code. For years, developers faced a stark choice: build expensive custom hardware, wrestle with complex kernel-mode drivers (risking Blue Screens of Death), or rely on brittle automation scripts that broke with every OS update.

HID devices are defined by report descriptors. The Tetherscript API allows you to load any custom report descriptor, meaning you are not limited to keyboards or mice. You can emulate:

At its core, the is a software development framework that allows Windows applications to create and manage virtual Human Interface Devices. Unlike USB hardware analyzers or physical loopback cables, this kit operates purely in software, injecting synthetic HID reports directly into the Windows input stack. In the world of software and hardware interaction,

A banking kiosk manufacturer tests touchscreen responsiveness by injecting precise stylus movements without wearing out physical hardware.

Flight simulators, medical training mannequins, and heavy equipment trainers often need custom control decks. Instead of building expensive USB hardware prototypes, developers use Tetherscript to emulate joysticks, throttle quadrants, and button boxes directly from simulation software.

For users with severe motor impairments, custom switch interfaces can be built as software. A single large button (physical) can trigger a Tetherscript-controlled virtual keyboard macro that types an entire sentence. The kit allows non-standard HID report sizes for specialized switches.

The company has hinted at future support for virtual USB-C PD (Power Delivery) HID bridges and deeper integration with Windows Core OS (Hololens 2).
