"The USB pads are the same port as the external USB connector. Most likely they are only used for convenience in Nokia's proprietary docking station."
So it looks like they are pins to the same usb controller and it only supports one port. It doesn't appear to be a second usb port but rather a different way to access the existing one.
is this link right? could you install the tilt stick this way or another usb device? I tried to search the forums and didn't see anything about it
so what wold it take to use the 2nd usb?
