I connect an external device that supports USB3.0 to an USB3.0 port on the computer/mother board using an USB 3.0 cable. I can see in the device manager that there are (intel) drivers that support USB3.0. The external device (WD mypassport) advertises USB 3.0 support. Is there a way to find out in windows 7 (home premium) if the actual usb connection is really using USB3.0 or if it is falling back into USB2? Is the transmission speed in the USB connection the only hint about what is happening in the USB connection. That is, a higher speed means that USB 3.0 is really being used?
