3.5 Enabling USB Ports for Windows® 7 Installation
Intel® new processors have removed their support for the Enhanced Host Controller
Interface (EHCI – USB2.0) and only kept the eXtensible Host Controller Interface
(XHCI – USB3.0). Due to that fact that XHCI is not included in the Windows 7
inbox drivers, users may nd it dicult to install Windows 7 operating system
because the USB ports on their motherboard won’t work. In order for the USB ports
to function properly, please create a Windows® 7 installation disk with the Intel®
USB 3.0 eXtensible Host Controller (xHCI) drivers packed into the ISO le.
Requirements
