What is the I2C HID Device Driver?

The I2C HID Device driver is a system driver used in Windows to support Human Interface Devices (HIDs) that communicate over the I2C (Inter-Integrated Circuit) protocol. This protocol is commonly used for connecting low-speed peripherals like touchscreens, sensors, and input devices (e.g., touchpads, fingerprint sensors, or accelerometers) to a computer's motherboard.

• HID (Human Interface Device) refers to devices that allow users to interact with a computer, such as keyboards, mice, touchscreens, and more.
• I2C is a serial communication protocol that allows multiple devices to communicate over a two-wire bus (data and clock lines), commonly used in embedded systems and low-power devices.

The I2C HID Device driver is required to ensure that Windows can recognize and communicate with these devices over the I2C interface. Without the correct driver, the device may not function properly, or you may see an error in the Device Manager (e.g., "This device cannot start" or "Code 10").
