3 Description
The TUSB8041 is a four-port USB 3.0 hub. It
provides simultaneous SuperSpeed USB and high-
speed/full-speed connections on the upstream port
and provides SuperSpeed USB, high-speed, full-
speed, 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. When the upstream port is connected to an
electrical environment that only supports full-
speed/low-speed connections, SuperSpeed USB and
high-speed connectivity are disabled on the
downstream ports.
