USB 3.2 Gen 1 Sharing Switch ATEN US4324 — 2x Host to 4x Device, USB-A/USB-C interfaces, 5 Gbit/s

The ATEN US4324 is a compact USB 3.2 Gen 1 (5 Gbit/s) sharing switch that lets two host computers share up to four USB peripherals. It supports a mix of USB-A and USB-C devices and is bus-powered for simple setups; an auxiliary USB-C power input is available when connected devices require additional power. The unit includes LED status indicators, a built-in pushbutton and a remote port selector for quick switching, and comes in a small black plastic enclosure with accent lighting.

Advantages

This sharing switch enables seamless swapping of control between two computers for connected devices, reducing desktop clutter and improving workflow efficiency. With USB 3.2 Gen 1 support it provides up to 5 Gbit/s SuperSpeed data transfer for compatible peripherals. The compact, portable housing with accent light and both USB-A and USB-C device ports gives flexible connectivity for a variety of modern peripherals. Bus-powered operation simplifies installation while the optional auxiliary USB-C power input ensures stable performance with power-hungry devices.

Suitable for

• Sharing external storage drives between two PCs
• Switching printers or multi-function devices between workstations
• Sharing webcams or headsets for video conferencing setups
• Connecting keyboards, mice and other USB peripherals to dual-computer environments

When it may not be suitable

The switch is not intended as a powered hub replacement for multiple high-current devices; bus power may be insufficient for several power-hungry peripherals simultaneously. In situations where all connected devices require sustained high power, a separate powered USB hub or connecting the auxiliary USB-C power adapter is recommended.

How to use

Connect the two host computers to the host ports, then attach up to four USB peripherals to the device ports using the appropriate USB-A or USB-C connectors. The switch powers on automatically when connected to a host; if connected peripherals require more power, plug a compatible USB-C power adapter into the auxiliary power input. Use the built-in pushbutton or the remote port selector to switch which host has control of the connected devices. Check the LED indicators to confirm active host and device status before transferring data or using peripherals.

What to consider before purchase

• Confirm connected peripherals’ power requirements — use the auxiliary USB-C power input if devices need extra power
• Ensure device compatibility with USB 3.2 Gen 1 (5 Gbit/s) for maximum transfer speeds
• Check that your setup requires sharing up to four USB devices between two hosts

Recommendations

For reliable operation with external drives and other power-demanding peripherals, connect a USB-C power adapter to the auxiliary power input. Always verify LED indicators when switching hosts and safely eject storage devices from the active host before switching control.
