UGREEN USB 2.0 Sharing Switch 2 Computer 1 Device

What this switch does

The UGREEN USB 2.0 sharing switch lets two computers take turns controlling a single USB device such as a printer, scanner or plotter. A single button toggles ownership and LED indicators show which system is active. No drivers are required on any supported computer. The box includes two USB 2.0 male cables for immediate connection.

Suitable setups and limits

This switch suits offices or home labs that want to share one peripheral between two machines without unplugging cables. It is not for users who need simultaneous access from both computers or who want to share more than one device unless an additional hub is attached. The supplier notes that cable runs should stay under three metres for reliable data transfer.

Behaviour under load

The switch passes standard USB 2.0 signals, so sustained transfers run at the host controller’s bulk-endpoint rate rather than a short burst speed. The unit draws power from the 5 V USB bus; the supplier warns that any source exceeding 5 V may degrade performance or damage the adapter. No active cooling or external power supply is involved.
