Did you plug in the front panel USB connector into the right spot. If so, then you might need to install some drivers for your case or motherboard. If not then take the cord and plug it into the first USB connection on the board. It will be labeled.
As i stated i my original question, the pendrives are being acknowledged by my computer only my computer is saying that the device is not recognised, so the front panel USB's are connected to the motherboard. Furthermore I installed LATEST chipset drivers from ASUS, no help there.
