Windows natively utilizes many HID controls, exposing hardware integration-points to enhance user-experience. While HID is a well-understood industry standard, the great flexibility of HID Report descriptors introduces complexity for the consumer (e.g. Applications, Hosts) to parse and support, so only a subset of what HIDs can describe may be supported (with great variance amongst consumers). The inevitability of errors/deviations in shipped device/consumer implementations from the HID-spec and the need to maintain backwards compatibility, further reduce what can be usefully described.
This project provides reference-implementations of HIDs that Windows natively consumes as hardware integration-points (e.g. Shell-interaction, Application-WindowMessages, UserMode APIs). (Note: 3rd-Party applications are naturally not limited to only what Windows natively consumes). References document (inline) any Windows expectations/limitations/work-arounds, and generally why things are the way they are.
References are intended to be used as a starting-point for 3rd-Party HID vendors, and to be consumed as-is by hobbyists.
This project is available as a library via the Arduino Package Manager. Search for

Additional devices will be continually added over the coming months. To make suggestions for the next device-type, please file an issue.
- Consumer Control (see
Microsoft_HidConsumerControl.h) - LampArray (see
Microsoft_HidLampArray.h)- New support in Windows as part of Dynamic Lighting
- System Control (see
Microsoft_HidSystemControl.h) - Telephony Headset (see
Microsoft_HidTelephonyHeadset.h) - Wireless Radio Control (see
Microsoft_HidWirelessRadioControl.h)
- Untested against non-Windows systems (e.g. macOS, Linux, etc…)
- Comprehension/simplicity was always chosen over efficiency (e.g. multiple Reports used, where one would be sufficient). See HID-spec and Waratah for rolling-your-own Report Descriptor.
- A subset of HID Report Descriptor variations within the HID-spec are naturally supported, but likely not all.
- Documented expectations/work-arounds may change at any time, and do not guarantee compatibility.
