This USB 3.0 switch allows two computers to share one USB device, such as a printer, scanner, mouse, keyboard, card reader, flash drive, and other USB devices. This 2 in 1 out USB 3.0 switch is not a bidirectional USB switch and therefore does not support 1 in 2 out functionality.
The USB 3.0 switch supports ultra-fast USB 3.0 data transfer and is backward compatible with USB 2.0 and USB 1.1 devices. Save time and improve efficiency.
The "SWITCH/5V" interface is used for power or an external control button. DC5V power is not normally required unless USB connection is unstable. You can connect an external control button if the port is not powered by a 5V power supply.
This USB 3.0 switch offers excellent compatibility, driver-free support for Windows 10/8/8.1/7/Vista/XP, Mac OS X, Linux, and Chrome OS, and is simply plug-and-play. The LED indicator makes it easy to see which computer is in control.
Our USB 3.0 switch works with all USB 3.0 devices. Please note that an external 5V adapter is required when using a high-power USB device. (Power adapter not included).
