The Intel® Serial IO UART Host Controller - 5AEE is a driver for a hardware component found on systems with Intel processors, typically Intel's newer generations (such as Skylake, Kaby Lake, or later). This driver supports the UART (Universal Asynchronous Receiver/Transmitter) interface, which is used for serial communication with peripherals like modems, microcontrollers, and other serial devices.

The UART Host Controller is part of the Intel Serial IO technology that allows the system to communicate with connected devices using the UART protocol, which is commonly used for low-speed data transfer.

How to Install the Intel® Serial IO UART Host Controller - 5AEE Driver:

1. Check Device Manager for Missing or Outdated Driver:

   • Press Windows Key + X and select Device Manager.
   • In Device Manager, expand the System Devices section.
   • Look for an entry named Intel® Serial IO UART Host Controller - 5AEE.
