Sigh. So many links, so much reading, and not one to the USB spec (that I found by skimming and searching). It's not just this article, but seemingly every 'deep dive does it'. Why do people read everything on the Internet, no matter the source and quality, but skip (what is usually) the best, most important source?
Absolutely; and pleasing an audience of one (me) isn't a great business move. Thanks for your exceptional effort.

I think people learn more from this kind of inductive approach.
Sometimes, but I often find them to be pretty good, and if I look at third party sources first, I usually wish I'd come to the spec much sooner in the process; the actual spec tends to make most third party sources redundant or plainly erroneous.
But of course, not all specs are equal; some are unreadable or poor introductions.
Most of the time when I want to hack on something, a super high level abstraction is more than sufficient for my needs (eg. don't need to understand the inner workings of a CPU if all I need is an API). But then there are those times when the spec, in all it's verbose rawness, is the perfect tool for the job.
