The device can provide USB high speed or full speed connection on the uplink port. The device also provides USB high-speed, full-speed, or low-speed connections on the downlink port. When the uplink port is connected to an electrical environment that supports only high-speed, full-speed, and low-speed connections, the high-speed, full-speed, and low-speed USB connections on the downlink port are enabled. When the uplink port is connected to an electrical environment that supports only full or low speed connections, the USB high-speed connection on the downlink port is disabled. USB 3.0 Hubs is higher than usb 2.0 in terms of transmitting data.
