The Radio HID Mini-driver is a type of driver used by certain wireless devices that communicate using Human Interface Device (HID) protocols, such as wireless keyboards, mice, or other input devices, that also use radio-frequency (RF) communication. These devices typically rely on a mini-driver to facilitate communication between the device and the computer running Windows.

The term "mini-driver" refers to a simplified or compact driver that provides basic functionality for the device, usually in situations where full-featured drivers are not required or needed for a minimal user experience. This driver works with devices that connect wirelessly via RF, such as through USB dongles or Bluetooth.
