Four-Port KVM for Two Computers

This BONAEVER switch connects four USB peripherals to two host computers with a single button press. It suits home-office workers and small-studio operators who share a keyboard, mouse, printer or scanner between a pair of machines. The unit requires no software drivers and draws power from the host USB ports, adding an optional micro-USB socket only for high-draw devices.

USB 2.0 Bandwidth Limit

All traffic passes through a USB 2.0 interface capped at 480 Mbps, so bulk endpoints such as external hard drives or high-resolution webcams will not reach their native throughput. The switch is driver-free across Windows 10 through XP, Mac OS, Linux and Chrome OS, but the 2.0 PHY remains the hard ceiling for every connected device regardless of host capability.

Four Shared Devices With One Active Host

Four downstream ports stay physically attached while the button toggles logical ownership between the two upstream ports; only one computer controls the peripherals at any moment. Users who need simultaneous access from both machines, or who require USB 3.x or 10 Gbps speeds for storage arrays, will find this topology and bandwidth insufficient.

Questions about this item

How many USB devices can I connect and share between the two computers?

You can connect up to four USB devices such as a keyboard, mouse, printer, scanner or flash drive and share them between two computers with a single button press.

What does the 480 Mbps transfer rate mean for my keyboard, mouse and printer?

The USB 2.0 link runs at up to 480 Mbps, which is more than enough bandwidth for standard peripherals like keyboards, mice, printers and scanners without noticeable lag.

Does the USB 2.0 interface limit which devices I can use on the switch?

The switch uses USB 2.0, so high-speed storage such as external SSDs will be capped at 480 Mbps, while keyboards, mice, printers and other standard peripherals work at full speed.
