Four-computer USB switch

The WRIARICH four-port USB 3.0 KVM switch lets up to four computers share a single set of four USB peripherals such as a keyboard, mouse, printer and webcam. A wired remote and front-panel buttons both change the active system with one click, while green LEDs show which computer is currently connected. It works with Windows, macOS, Chrome OS and Linux without extra drivers, making it suited for multi-system desks.

Passive operation with optional power

The unit draws all the power it needs from the host USB ports, so no external adapter is required for typical low-draw devices. A micro-USB charging port is included to stabilise higher-consumption peripherals such as external hard drives or headsets. Backward compatibility with USB 2.0 and 1.1 ensures older gear still functions, while the 3.0 interface delivers up to ten times the throughput of USB 2.0.

Compact hub with included cables

Measuring 3.94 by 2.56 by 0.47 inches and weighing 9.2 ounces, the switch fits in tight desk spaces and adds minimal cable bulk. The package supplies four 0.8-metre USB-A to USB-B cables for the computer links, a 1.5-metre wired remote for convenient placement, and a 1.5-metre USB power cord for the auxiliary charging port. Builders who need more than four computer ports or who require video switching will need a different solution.

Questions about this item

How do I connect the four computers to the switch, and which step do people often miss?

Plug each of the four included USB 3.0 cables into a computer's USB-A port and the matching USB-B port on the switch, then connect your four USB devices to the front ports; the step often missed is attaching the supplied USB power cord to the micro charging port so high-power devices such as hard drives remain stable.

What maintenance or replacement will this KVM need over time?

The unit has no moving parts or user-serviceable components; only the four 0.8 m USB 3.0 cables or the 1.5 m wired remote might need replacing if they become damaged.

What is the first limit I will hit during sustained file transfers?

The USB 3.0 interface caps throughput at 5 Gbps, so sustained transfers cannot exceed that bandwidth even if the attached drives are faster.
