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.
