More of a case of you have not turned on USB 2.0 support in the bios of the board. since the four back ports are USB 2.0 standard. If your are using a 2.0 Usb device without the option of 2.0 usb support turned on in the bios the device will not be seen by windows or the USB 2.0 ports.
Once done it may require you to find the driver for the usb 2.0 ports for the board.
It will work then.
Ok, I enable it and still nothing
