Introduction 1.1 Description AU6258 is a fully compliant with the USB 2.0 hub specification and is designed to work with USB host as a high-speed hub. Its built-in TT (Transaction Translator) allows system to benefit combinational performance under the unbalanced traffic condition. AU6258 supports four USB downstream ports and one upstream port. Each downstream port could be a device of high-speed, full-speed or low-speed traffic, while the upstream port supports both high-speed and full-speed traffic. In addition to the application as a stand-alone hub, AU6258 is also very suitable for using in notebook and motherboard design to provide additional USB port. All these product advantag.
