39// USB Descriptors are binary data which the USB host reads to
40// automatically detect a USB device's capabilities. The format
41// and meaning of every field is documented in numerous USB
42// standards. When working with USB descriptors, despite the
43// complexity of the standards and poor writing quality in many
44// of those documents, remember descriptors are nothing more
45// than constant binary data that tells the USB host what the
46// device can do. Computers will load drivers based on this data.
47// Those drivers then communicate on the endpoints specified by
48// the descriptors.
49
50// To configure a new combination of interfaces or make minor
51// changes to existing configuration (eg, change the name or ID
52// numbers), usually you would edit "usb_desc.h". This file
53// is meant to be configured by the header, so generally it is
54// only edited to add completely new USB interfaces or features.
