// USB Descriptors are binary data which the USB host reads to
// automatically detect a USB device's capabilities.  The format
// and meaning of every field is documented in numerous USB
// standards.  When working with USB descriptors, despite the
// complexity of the standards and poor writing quality in many
// of those documents, remember descriptors are nothing more
// than constant binary data that tells the USB host what the
// device can do.  Computers will load drivers based on this data.
// Those drivers then communicate on the endpoints specified by
// the descriptors.

// To configure a new combination of interfaces or make minor
// changes to existing configuration (eg, change the name or ID
// numbers), usually you would edit "usb_desc.h".  This file
// is meant to be configured by the header, so generally it is
// only edited to add completely new USB interfaces or features.
