The Universal Serial Bus (USB) is a serial interface designed to be plug-and-play making it easy to connect peripherals to a host. The following pages are intended to help the designer to get a better understanding about the USB protocol in general. They are divided into different pages as follows:

USB Network shows the topology of the USB network.
USB Transfer Rates gives a quick glance at the theoretical maximum data rates that are supported by USB.
USB Communication shows how data is exchanged on the USB bus.
USB Protocol page gives an overview over the protocol and the basic communication model.
USB Descriptors explains the data structure that is used in USB devices to report their attributes to a host. Most of these descriptors can be matched to configuration settings in MDK.
