## Long description

The StarTech.com ST3300U3S converts a single SuperSpeed USB 3.0 host port into a Gigabit RJ45 Ethernet port and adds a three-port USB 3.0 hub. The compact adapter provides wired network connectivity at 10/100/1000 Mbps and supplies three additional USB 3.0 ports for external storage or peripherals, supporting USB 3.0 data rates up to 5 Gbps. It is backward compatible with USB 2.0 and 1.x and can be used with or without the included external power adapter.
Advantages
This adapter delivers full Gigabit network performance over a USB 3.0 connection and supports advanced network features including Jumbo Frames, VLAN tagging and Wake on LAN (WoL). The integrated three-port USB 3.0 hub provides high-speed connectivity for external drives and peripherals and offers fast-charging support for mobile devices. The included cable length gives more reach than typical dongles, and the optional power adapter supplies sufficient power for higher-draw devices. The unit is compact and portable and comes with a two-year StarTech.com warranty and free lifetime technical support.
Suitable for
Adding Gigabit Ethernet to laptops or desktops without an RJ45 port
Expanding USB connectivity with three additional USB 3.0 ports

How to use
Connect the ST3300U3S to a computer’s SuperSpeed USB 3.0 port using the attached cable. Plug an Ethernet cable into the RJ45 port to access the network at Gigabit speeds. Attach USB devices to the three USB 3.0 hub ports for data transfer or charging. If additional power is required for high-power USB devices, connect the included external power adapter.
