Thank you for the clarification!

Well, when someone figures out a "standardized way for the controller chip to pass this info up" I hope they do it better than S.M.A.R.T. for disks.

There's also the issue that most USB cables are cheap junk that either is non compliant, or actively lying about it's capabilities. Which is hard to solve since anyone can sell USB cables without needing to pass testing.
