USB Host/Device

The Stellaris® family is the first to offer ARM® Cortex™-M3 microcontrollers with USB 2.0 Full Speed Host/Device capability. The integrated USB controller operates as a function controller for a full-speed or low-speed host or device in point-to-point or multipoint (hub) communications with USB functions. The controller complies with the USB 2.0 standard, which includes suspend and resume signaling.
