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, fullspeed,

and low-speed connections, the USB highspeed,

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 lowspeed

connections, the USB high-speed connectivity

are disabled on the downstream ports.
