...USB should be easy...

...caught my eye.

USB aka Useless Serial Bus.. is NOT EASY ! Just one of the 'USB for Dummies' book is over 600 pages. It's amazing that USB actually works when you look at just some of the hardware requirements and then the layers and layers and layers of code to just have device A say 'Hello' to device B. If it wasn't for lightning fast computers, USB could not exist.
Yeah, I'm old...still love RS-232. Small tight code with real interrupts. Then again I understand ASR-33s. I tip my hat off to all who can actually get USB to do their bidding!

If you look at the post he shows as a 'quote' when saying this, Newguy was making exactly this point (much easier to use a device/module for this). However this post is then quoted, and followed with the comment about 'USB should be easy'. 90% of the USB code I see here, will not work properly if the host wants to go into a power saving state. Getting USB to work properly does require a lot more 'low level' knowledge that is really desirable. USB shows all it's history of 'committee design', then combined with multiple generations of changes, often being led by almost an opposite of Darwinian evolution (survival of the worst...).
