I happened to notice these same errors on an arm64 server in our lab, running the 4.15.0-73-generic kernel. (A Cavium crb2s system named 'recht'). While this could be unrelated - perhaps an actual bad USB cable - it isn't an error I'd noticed before on this system, and it happened to be running a kernel containing the offending commit. The system is currently in-use, but I can check to see how reproducible it is once it is freed up.
