// Dear inquisitive reader, USB is a complex protocol defined with
// very specific terminology. To have any chance of understand this
// source code, you absolutely must have solid knowledge of specific
// USB terms such as host, device, endpoint, pipe, enumeration....
// You really must also have at least a basic knowledge of the
// different USB transfers: control, bulk, interrupt, isochronous.
//
// The USB 2.0 specification explains these in chapter 4 (pages 15
// to 24), and provides more detail in the first part of chapter 5
// (pages 25 to 55). The USB spec is published for free at
// www.usb.org. Here is a convenient link to just the main PDF:
//
// https://www.pjrc.com/teensy/beta/usb20.pdf
//
// This is a huge file, but chapter 4 is short and easy to read.
// If you're not familiar with the USB lingo, please do yourself
// a favor by reading at least chapter 4 to get up to speed on the
// meaning of these important USB concepts and terminology.
//
// If you wish to ask questions (which belong on the forum, not
// github issues) or discuss development of this library, you
// ABSOLUTELY MUST know the basic USB terminology from chapter 4.
// Please repect other people's valuable time & effort by making
// your best effort to read chapter 4 before asking USB questions!
// Uncomment this line to see lots of debugging info!
