Pros & Cons

Pros

  • ✓ Separate hand switch sits at your fingertips instead of behind the desk
  • ✓ USB-A on the computer side works with laptops that have no PS/2 ports

  • ✗ Integrated cable means no swapping in a longer run if the PCs sit apart
  • ✗ USB 2.0 / 1.1 spec, so no high-polling-rate gaming peripheral headroom

Manufacturer description

The Elecom KM-A22BBK is a two-port USB KVM switch built for one job: sharing a single keyboard and mouse between two computers without touching a second desk setup. Both computer-side connections are USB-A male, so it works with modern laptops that have no PS/2 ports at all — useful when you are pairing a retro build with a current machine, or a work laptop with a home desktop. The peripheral side offers two USB-A female ports for your keyboard and mouse, and the switch passes through multi-button mice with tilt-wheel support and hot-key keyboards rather than stripping them down to basic HID…

Frequently Asked Questions

Does this switch my monitors too, or just the keyboard and mouse?

Keyboard and mouse only. The peripheral side is two USB-A female ports, and there is no video connector on the unit, so each computer keeps its own display.

Will it work with my laptop that has no PS/2 ports?

Yes. The computer side is USB-A male x 2, so it connects to any machine with two free USB ports; PS/2 is not required on either computer.

Do I need to install software or drivers?

No. Elecom lists it as plug and play with no driver installation, so both computers recognize the shared keyboard and mouse on connection.

Will my gaming mouse with extra buttons and a tilt wheel still work?

Elecom states the switch supports multi-function mice with tilt-wheel and multi-button features, plus multi-function keyboards with hot keys.

What operating systems does it support?

Windows 10/8.1/8/7/Vista/XP/2000 on PC/AT compatibles, and Mac OS X 10.3 or later, macOS 10.12 or later on Intel Macs, plus PowerPC Macs on OS X 10.0-10.5.

Key Features

  • This is a keyboard and mouse computer switcher that allows you to share one set of USB devices such as keyboards and mouses
