If you need to use a metal hanger to push down the usb cable down that hole, use it. I almost had to use it.
That hole is blocked in the n55. you are talking about the hole below the ecu fan hole correct? The USB cable doesn't fit in the hole. I was able to unscrew the 4 large torx screwdrivers and move the box out to push the wire down but I didn't see the wire underneath.
