+// USB Descriptors are binary data which the USB host reads to

+// 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

-// 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.
