https://www.microsoft.com/en-us/download/details.aspx?id=38423
B.2 <USB3.0 driver>
Before Win7 install the USB3.0 driver or use in Win8 and Win8.1, xHCI
needs to be enabled in the BIOS.
Note that if enable xHCI, all USB port will unusable in Win7. So first need
copy driver folder to your HDD, then enable xHCI, and use PS/2 to do install.
