UGREEN 30768 2-PC 4-Port USB 3.0 Sharing Switch

Overview

The UGREEN 30768 lets two computers take turns using up to four USB devices at USB 3.0 speed. Both computers connect to it with the supplied cables; a printer, keyboard, mouse, scanner or external drive plugs into the four USB-A ports, and one button hands the whole set to the other computer, with two LEDs showing which one is active. It suits a desk where a laptop and a desktop share one printer, one keyboard set and a fast drive.

Is it right for you?

• Suits keyboards, mice, receivers, printers, scanners, card readers and external drives shared between two computers.
• USB 3.0 at up to 5 Gbps shared across the devices, so external drives transfer quickly.
• It does not switch a monitor. If the screen should follow too, choose a KVM (keyboard, video and mouse) switch.
• One computer controls the devices at a time, and there is no automatic switching.
• A USB-C-only computer needs a data-capable USB-C to USB-A adapter or dock for its host link.

Key features

• Two computer inputs and four USB-A peripheral ports.
• USB 3.0 data up to 5 Gbps on a compatible path.
• One button changes the active computer, with two LED indicators.
• Micro-USB 5 V auxiliary power input for demanding setups, from a separate regulated supply.
• Two USB-A to USB-A host cables of about 1.5 m in the box.
• No switch software needed; every peripheral must work on both computers.
• Metal housing, 10.4 x 5.1 x 1.5 cm, 200 g.

What else you need

• Two computers with a USB-A host port each, or a data-capable USB-C to USB-A adapter.
• Only for demanding setups: a regulated 5 V supply and Micro-USB cable for the auxiliary power input. The power cable and adapter are not included.

Installation

No installation is needed. Connect each computer with a supplied cable and plug the devices into the four ports.

Before you buy

• Eject mounted storage and wait for activity to finish before switching, or open files can be corrupted.
• Close printer and scanner programs before switching, since they can hold jobs or locks.
• The 5 Gbps figure is a shared ceiling, not a per-port guarantee.
• Auxiliary power must be regulated 5 V through Micro-USB; wrong voltage or polarity can harm connected equipment. The Micro-USB socket is not for charging phones or laptops.
• Switching may wake a computer, change the default audio device or reassign drive letters, depending on the operating system.
• Webcams, audio interfaces and licensed or security devices only work if they tolerate disconnecting and reconnecting and have drivers on both computers.
• Stop using the switch if a port is loose, the housing becomes abnormally hot or a cable causes intermittent connection.
