I now believe this is a hardware problem. The specific device was powered down (and right now it has dead batteries) and I was not used to seeing errors with powered down USB devices. However this device had other flakey behavior in the past where I had to unplug and replug the USB connection to get it working on occasion. I also went back to 3.13 and was still seeing the problem when I don't remember seeing it when I was actually using 3.13.
