+// 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.
