It doesn't look very clever does it. You'd have thought that they'd have the sense to fit it horizontally so that clearance isn't an issue with any cable. Most USB cables will need 30-40mm above the socket.
But on looking at the picture again, the top of the socket seems to to be on a level with the base of the ECU which has a great big connector sticking out the side over the top of the frame tube. It also has what looks like a couple of relays mounted at the rear of it. So there may be more room than we think.
