If you hold the Pro Plus with the face pointing upwards and the connector of the USB cable to where the word Oceanic is pointing up, slide the connector into the slot from the side. The bottom of the USB connector should be flush with the bottom of the computer at that point. It's funny that I read this tonight, as I just got my cable yesterday and had to figure it out tonight. All the setting transferred from the PC to the Pro Plus, no problem. Just make sure you put the Pro Plus in transfer mode... hold both buttons down till Set 1 is displayed, then hit the left button 4 times. Once you do that, you can initiate the transfer from the PC. Hope this helps!
