UGREEN 4-Port USB 3.0 Sharing Switch for 2 Computers (15705)

Overview

The UGREEN 15705 lets two computers take turns using a set of up to four USB devices. Both computers connect with the supplied USB-A cables; a printer, keyboard, mouse, scanner, webcam or drive plugs into the three USB-A and one USB-C port, and the top button or the 1.5 m wired remote hands the whole set to the other computer. It suits a desk where a laptop and a desktop share one printer and one keyboard without a second set of cables.

Is it right for you?

• Suits USB sharing only; it does not switch a monitor. If you need the screen to follow too, choose a KVM (keyboard, video and mouse) switch.
• One computer controls the devices at a time; both cannot use the same device together.
• Up to 5 Gbps shared across the connected devices, enough for drives and webcams, but the bandwidth is shared.
• A USB-C-only computer needs a data-capable USB-C to USB-A adapter for its host link.
• The programs you use must tolerate the devices disconnecting and reconnecting when you switch.

Key features

• Two computer inputs and four downstream ports: three USB-A and one USB-C.
• USB 3.0 at up to 5 Gbps, backward compatible with USB 2.0 and USB 1.1 devices at their own speed.
• Switching from the top button or the included 1.5 m wired remote.
• Dedicated USB-C power-only input to stabilise high-current devices from a suitable external source.
• No driver needed on Windows, macOS, Linux or ChromeOS; peripherals still use their own drivers.
• Aluminium shell, 356 g.

What else you need

• Two computers with USB-A host ports; the two USB-A to USB-A cables are in the box. A USB-C-only host needs a compatible data adapter.
• Only if you connect high-current devices: a suitable 5 V USB-C power source and cable for the power input. The package does not list a power adapter or USB-C power cable.

Installation

No installation is needed. Connect each computer with a supplied cable, plug the devices into the four ports and place the wired remote within reach.

Before you buy

• Switching interrupts the USB connection, so finish print jobs, recordings and firmware updates and eject drives before you switch.
• USB 3.x activity can interfere with nearby 2.4 GHz wireless receivers; move the receiver further away if a mouse or keyboard stutters.
• The USB-C power socket is not a fifth data port and not a computer input.
• Specialised devices such as security dongles may bind to one program or policy and may not reconnect cleanly after every switch.
• The 5 Gbps link is shared, so actual throughput can be lower with several active devices.
