xHCI (eXtensible Host Controller Interface) is a specification for a USB host controller interface that was introduced in 2008. It is designed to provide a more efficient and scalable way to manage USB devices, compared to earlier USB host controller interfaces such as EHCI (Enhanced Host Controller Interface) and UHCI (Universal Host Controller Interface). xHCI supports multiple USB devices, improved power management, and faster data transfer rates.
Before diving into troubleshooting, it helps to understand what the xHCI compliant host controller actually does. Traditional USB controllers used the (Open Host Controller Interface) or UHCI (Universal Host Controller Interface) standards for USB 1.1, later replaced by EHCI (Enhanced Host Controller Interface) for USB 2.0. However, EHCI had limitations: it could not directly handle USB 3.0 SuperSpeed connections and required separate companion controllers to manage legacy USB 1.1/2.0 devices. usb xhci compliant host controller driver windows 10 64 bit
