Four-Computer USB 3.0 KVM Switch

This FOCUSTEC KVM switch lets four computers share four USB 3.0 peripherals without unplugging cables or configuring network shares. It targets users who operate multiple PCs, Macs or Linux machines and need instant access to a printer, scanner, keyboard, mouse or flash drive. Driver-free operation keeps setup simple across supported operating systems.

Plug-and-Play Installation

Connect each computer using the supplied USB 3.0 cables and power the switch via the included Micro USB cable; no software or drivers are required. Individual push buttons with LED indicators select the active computer instantly. The only common issue is forgetting to provide external power, which can cause unstable device recognition on high-draw peripherals.

USB 3.0 Bandwidth Shared Across Four Ports

The switch passes USB 3.0 signals, so each connected device negotiates up to the standard’s 5 Gbps link, but total throughput is divided among the four downstream ports when used simultaneously. High-throughput devices such as external SSDs may see reduced speeds during concurrent transfers. The unit does not support video switching, so separate display connections remain necessary.

  • Works driver-free with Windows, macOS and Linux for plug-and-play convenience
