USB 2.0 Hubs

USB 2.0 is a USB interface standard released in 2000 with a theoretical maximum transmission speed of 480Mbps (about 60MB/s). The port has four cables (five cables for MicroUSB and MiniUSB), and the maximum output current is 0.5A. USB 2.0 is currently the most common version of USB port, almost all computers have USB 2.0 port, most USB devices also support USB 2.0. USB 2.0 hub. 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.
