The Intel USB 3.0 eXtensible Host Controller Driver 1.0.8.251 is a critical software component that enables communication between your computer’s operating system and USB 3.0 devices connected to Intel chipsets. This article provides comprehensive information about this driver version, including its supported hardware, operating systems, components, key updates, and language support. Understanding this driver is crucial for ensuring optimal performance and compatibility of your USB 3.0 peripherals.
What is an eXtensible Host Controller Driver (xHCI)?
Before diving into the specifics of version 1.0.8.251, it’s essential to understand what an xHCI driver does. The xHCI, or eXtensible Host Controller Interface, is a standard specification that defines how a USB host controller (the hardware that manages USB connections) should interact with the operating system. The driver acts as a translator, allowing the OS to understand and control the host controller. This, in turn, enables the proper functioning of USB devices. Without the correct xHCI driver, USB 3.0 devices might not function at all, or they might operate at reduced speeds, often reverting to USB 2.0 functionality.
Supported Hardware (Intel Chipsets/Processors)
The Intel USB 3.0 eXtensible Host Controller Driver 1.0.8.251 is designed to work with a specific range of Intel chipsets and processors. While the exact list isn’t provided in the source material, generally, these drivers support:
- Intel 7 Series Chipset Family
- Intel 8 Series Chipset Family
- Intel 9 Series Chipset Family
- Corresponding Intel Core Processors (e.g., 3rd, 4th, and 5th generation Intel Core processors)
It’s crucial to verify compatibility with your specific chipset before installing this driver. Refer to your motherboard or system manufacturer’s documentation for a definitive list of supported chipsets. Installing an incompatible driver can lead to system instability or device malfunction.
