Excessive power line noise causes the 2414U to get confused or bogged down enough that its USB communication starts to fail. I don't know the technical details of why, but I do know that it can happen. Some customers with the exact error you are seeing resolve it by removing or isolating power line noise (often, but not always, by using a FilterLinc on a UPS).
