4-Port USB 2.0 KVM Switch

The WRIARICH switch lets two computers share four USB 2.0 peripherals with a single button press. It suits home users and small offices that want to keep a keyboard, mouse, printer and scanner connected to both systems without unplugging cables. No drivers are required on Windows, macOS, Linux or Chrome OS. The unit draws power from the USB bus and includes an optional micro-USB port for an external 5 V adapter.

Replaces Manual Cable Swapping

This device removes the need to physically move USB plugs when changing between two computers. The upgrade is worth it when you regularly use the same four peripherals across both machines and want instant switching with LED indication. It does not serve setups that require simultaneous access from both computers or that need more than four shared devices.

Sustained Operation With Optional Power

Under continuous use the switch remains stable for standard peripherals such as keyboards, mice and flash drives. For higher-draw devices like external hard drives or SSDs the optional 5 V adapter ensures reliable connectivity during long sessions. The bus-powered design handles typical office loads without extra cabling.
