I can’t offer much insight into the standard ST driver other than to say that if it is also having this dropout issue, the cause is probably in the ST firmware itself. It also lines up with them recently updating their hub.
I plan to dig through their updates and see if any of them looks like it could be the culprit.
No. If you are happy, I’d leave it be. If it happens again, you’re fine to grab logs at that point. I don’t need to see the “trigger” for something like this. Whatever error you were getting would likely stay in the logs well after it started.
