Let's begin with an overview of USB hubs. A USB hub is a device that allows users to connect multiple USB peripherals and devices to a single USB port on a computer or other electronic equipment. The USB controller hub allows for port replication, to replicate from one port to many, or port relocation, to relocate from one board to another. It operates at top speeds while still being backward-compatible with lower speeds. The EZ-USB™ HX3 comes in three different package sizes. The most common applications are in automotive infotainment systems as a port replicator, computers, and peripherals, including docking stations, LCD TVs, set-top-boxes, gaming consoles, home gateways, Wi-Fi routers, storage, printing, and media servers. USB hubs are an integral part of the customer's everyday life.
