USBDK report wrong USB speed under win7 #61

I have issue with USBDK under windows 7 with the latest USBDK. It seems that USBDK will report a working super speed device as a high speed device. I have tried other backends of libusb (WinUSB) and it reports correct usb speed.

I have tested it on a laptop and QEMU(virt-manager with USB 3.0 host controller) with a host controller driver of version 2.1.39.0. I will post a trace log soon.

Which USB3 controller drivers you installed for USB3 controller? (If I'm not mistaken, Windows does not provide drivers for USB3 controller via Win7 Windows Update).

Driver is provided by renesas.
