USB xHCI Compliant Host Controller Driver in Windows 10 (64-bit): The Complete Guide Introduction If you've ever opened Device Manager on a Windows 10 64-bit PC, you’ve likely seen the entry "USB xHCI Compliant Host Controller" under the Universal Serial Bus controllers section. Despite its technical-sounding name, this driver is one of the most critical components for modern USB functionality. Without it, your USB 3.0, 3.1, and even 3.2 ports would either not work at all or fall back to slower speeds. This article explains what the xHCI driver is, why it matters for Windows 10 64-bit, common problems, and how to fix or update it properly.
What is xHCI? xHCI stands for eXtensible Host Controller Interface . It is the industry standard controller interface for USB 3.0, 3.1, and 3.2. Unlike its predecessors:
UHCI (Universal Host Controller Interface) – USB 1.0/1.1 (Intel) OHCI (Open Host Controller Interface) – USB 1.1 (non-Intel) EHCI (Enhanced Host Controller Interface) – USB 2.0
…xHCI was designed to handle all USB speeds (1.x, 2.0, 3.x) within a single controller. This simplifies hardware and driver design. usb xhci compliant host controller driver windows 10 64 bit
Key point: Windows 10 64-bit relies exclusively on the Microsoft inbox xHCI driver for native USB 3.x support.
The Driver: usbxhci.sys On Windows 10 64-bit , the primary driver file is:
usbxhci.sys – located in C:\Windows\System32\drivers\ USB xHCI Compliant Host Controller Driver in Windows
It is a Microsoft native driver provided inbox with Windows 10. For most users, this is the only driver needed. Unlike older Windows versions (e.g., Windows 7), Windows 10 does not require vendor-specific xHCI drivers from Intel, AMD, or ASMedia for basic functionality. Driver Details (typical):
Driver Provider: Microsoft Driver Date: Often 4/21/2021 or later (varies by Windows build) Driver Version: 10.0.19041.x (for Windows 10 20H2 and newer) Digital Signer: Microsoft Windows
Why the xHCI Driver Matters Without a correctly functioning xHCI driver on Windows 10 64-bit: This article explains what the xHCI driver is,
USB 3.x ports will operate at USB 2.0 speeds (480 Mbps max). High-power devices (external SSDs, USB hubs, docks) may disconnect or fail. USB devices requiring >500mA (e.g., bus-powered external HDDs) may not initialize. USB-C and Thunderbolt 3/4 docks with USB 3.x passthrough may malfunction. VR headsets (Oculus Rift S, HP Reverb G2) will show errors.
Note: The xHCI driver also controls USB Selective Suspend , which saves power but can cause disconnection issues with some devices.
