Windows 7 does not have support for USB3 (xHCI). It says so in the manual Chapter 3.2 (you read it, right?). You'll have to download the Intel drivers. Don't have the link available, search for it.

It was new for me to install a physical driver in an virtual machine, but it works perfect!

Thanks a lot
