acchow is disagreeing with your database query likeness. Your comment was effectively saying that it's just waiting until it's ready. And this is clearly something that can be disagreed with.

Based on the way this article is worded, it seems like there is no way to check when TRSMRCY is over. Imagine if you were waiting for a database query and if the database wasn't done thinking yet, simply accessing the socket would make the query abort.

Your understanding of the problem is in error, and will be corrected by reading the linux-usb thread linked to by the article.

Good! But that doesn't mean your original comment was infallible, since it didn't actually clarify such a thing.
