3 Description

The TUSB4041I device is a four-port USB 2.0 hub.

The device provides USB high-speed or full-speed

connections on the upstream port. The device also

provides 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, full-

speed, and low-speed connections, the USB high-

speed, full-speed and low-speed connectivity is

enabled

on

the

downstream

ports.

When

the

upstream

port

is

connected

to

an

electrical

environment that only supports full-speed or low-

speed connections, the USB high-speed connectivity

are disabled on the downstream ports.
