WRIARICH USB 3.0 4-Port KVM Switch 2-to-4

Share 4 USB 3.0 Devices Between Two Systems

This USB 3.0 KVM switch lets two computers share up to four peripherals such as a printer, scanner, mouse, keyboard or USB disk. It is designed for small offices or home setups where multiple PCs or Macs need access to the same devices. No external power supply is required because the unit draws power from the USB bus. Installation is plug-and-play with no driver installation needed.

4-Port USB 3.0 Switch Selector

The single specification that decides fit is the four USB 3.0 ports available for sharing between two connected systems. This port count determines how many peripherals you can keep permanently attached without swapping cables. The switch supports USB 3.0 data rates for compatible devices. It is not suited for users who need to share peripherals across more than two computers or who require more than four downstream ports.

Bus-Powered Operation Under Sustained Load

Because the switch is bus-powered, it relies on the host computers to supply enough current for all four connected peripherals during continuous use. High-draw devices such as bus-powered hard drives may exceed the available power budget when used simultaneously. The unit contains no internal fan or active cooling, so thermal performance depends on ambient airflow. It is not intended for setups that demand guaranteed power delivery to every port under heavy sustained transfer loads.
