HID

HID (Human Interface Device) is the universal USB-IF specification enabling instant, driverless plug-and-play functionality for peripherals like keyboards, mice, and game controllers.

HID (Human Interface Device) is the foundational USB-IF device class specification: it standardizes communication for peripherals, ensuring true plug-and-play capability. Proposed by Microsoft's Mike Van Flandern, the standard (currently v1.11) eliminates the need for custom drivers on host systems (PC, mobile, tablet). It achieves this by requiring the device (like a keyboard, mouse, or game controller) to self-describe its data format and capabilities to the host via a Report Descriptor. This compact, extensible protocol simplifies hardware development and guarantees interoperability across platforms (Windows, macOS, Linux).
