WRIARICH USB 2.0 KVM Switch 4 Ports 4 Cables

Four-Port USB 2.0 KVM for Two Systems

This KVM switch lets two computers share up to four USB 2.0 peripherals such as keyboards, mice, printers or external drives. It is aimed at home users and small offices that want to avoid unplugging cables or configuring network sharing software. The unit is bus-powered, so no external adapter is required. Simply press the button to toggle control between the connected PCs or Macs.

Check Port Count and Cable Reach

Verify that each computer has a free USB Type-A port for the included cables. The package supplies four USB A-to-A cables, so both systems need two ports each to use every peripheral slot. Ensure the cable length suits your desk layout because the switch itself has no integrated cable management. No driver installation is needed, but confirm that your operating systems support standard USB 2.0 HID and mass-storage classes.

Steady Sharing Under Constant Use

Because the switch draws power from the USB bus, it remains active as long as at least one host is powered on. The mechanical button provides a definite click, preventing accidental toggling during long work sessions. All four downstream ports stay enabled on the selected host, so printers can complete large jobs and external drives can transfer data without interruption. There is no automatic switching or timeout that would disrupt sustained workflows.
