I just read from another post from the same section 512 that the person is also having problems with the 3.0 usb ports. Therfore, it seems that there is a problem with 3.0 ports on Windows based computers. Do you have any updated drivers for usb 3.0 ports for Windows based computers?
Windows 8 64 bit, Asus VivoBook X202E, 1 USB 3.0 port and 2 USB 2.0 ports.
I have connected my XFactor to all of these ports, every time the device driver says "This device cannot start. Code 10. A request for the USB device descriptor failed."
