Tusb8041rgcr USB chip four Port USB 3.0 hub
explain
Tusb8041 is a four Port USB 3.0 hub. The device can provide synchronous ultra fast and high-speed / full speed USB connection on the uplink port,
Ultra fast, high-speed, full speed or low-speed USB connection can be provided on the downlink port. When the uplink port is connected to an electrical environment that only supports high-speed or full speed / low-speed connections, the ultra fast USB connection on the downlink port is disabled. When the uplink port is connected to an electrical environment that only supports full speed / low speed connection, the ultra fast USB and high-speed connection on the downlink port are disabled.
characteristic
• four Port USB 3.0 hub
