Enabling Usb Ports For Windows® 7 Installation - ASROCK Z270M-ITX/AC User Manual

3.4 Enabling USB Ports for Windows® 7 Installation
Intel® new processors have removed 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 find it difficult 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
file.
