Report superspeed properly on Win7
Win7 with USB 3.0 stack might not report superspeed
the same way as Win8 does. Use bcdUSB field of device
descriptor for that (USB 3.0 device connected to USB 2.x
port usually falls to USB 2 compatible configuration).
Getting the speed from HUB driver via IOCTL is more
complicated.
