About this course

This class will enable an engineer with no prior USB hub knowledge to successfully design systems with USB2 hubs. The material explained in this class will reduce time to market and board re-spins for USB2 hub hardware designs. The functional blocks which make up a USB2 hub, as well as the principles of operation are explained. The key configuration parameters for a USB2 hub are described so that system designers can make informed decisions on their hardware design. Finally, the class is concluded with common debugging issues and techniques for rapid root cause analysis and resolution.
