2 Applications Computer Systems, Docking Stations, Monitors, Set-Top Boxes 3 Description The TUSB8042 is a four-port USB 3.1 Gen1 hub. It provides simultaneous SuperSpeed USB and highspeed/full-speed connections on the upstream port and provides SuperSpeed USB, high-speed, fullspeed, or low-speed connections on the downstream ports. When the upstream port is connected to an electrical environment that only supports high-speed or full-speed/low-speed connections, SuperSpeed USB connectivity is disabled on the downstream ports.
