Perixx PERIPRO-401 PS2 to USB Adapter for Keyboard and Mouse - Built-in USB Controller - Black

Works fine with proper hookup sequence . Hook up the adapter alone to your USB port, let the PC recognize it, and then plug in your PS2 keyboard.

These PS2 / USB adapters are hit or miss, no matter which brand you buy. This Perixx model is no exception - it worked on a Lenovo mini PC but had issues on an older Gigabyte motherboard with a single PS2 port that accepts either mouse OR keyboard. (I had a PS2-only KVM set up on a test bench). I am not putting fault completely with the adapter, but let this be a buyer beware warning.

Works as expected.

Makes my ps/2 keyboard work. A simple pin adapter was not working. This is what you need to make sure that the old keyboards work on usb port

If a passive adaptor did not work for you, this active converter should. I have a HP15 notebook (laptop bought in 2016) & wanted to connect an external keyboard that was over 10 years old. I understand some newer keyboards/computers may work with the passive adaptor, but the active converter has a chip in it.

Works great. I use it only for my old PS/2 keyboard outlet. I guess should work good with the old ball mouse.

This product works just as intended. Im very happy that I can still use my older trackball with my newer computer which doesnt have any serial ports, only USB ports

I bought two (2) of these adapters. The adapter appears to be well made. It wasnt what I thought I ordered for the purpose I had in mind at the moment I ordered; however, there was an old PS/2 IBM real keyboard that has been sitting around waiting to be used. It was to replace the AWFUL plastic piece-of-junk, less than full size, USB keyboard that came with the latest computer purchase. I also had an optical mouse with a PS/2 connector that replaced the horrid roller ball mouse that also came with the latest computer purchase. So the oops order became the order that allowed me use quality equipment from the olden days. Im happy, I gave five (5) stars, and now I can really type on the full-size keyboard and use a mouse that does not skip. BTW, the adapter works!

Allows use of PS2 keyboard and mouse on newer computers that only have USB ports and no PS2 ports. Unfortunately you cannot use the keyboard to wake pc from sleep if you do not want the mouse to also wake pc from sleep. I have a Microsoft optical mouse and even though I configure the mouse not to wake the computer and the keyboard to wake the computer, the computer will not stay in sleep mode. If I configure both the keyboard and mouse not to wake the computer it will remain in sleep mode but I have to press the power button to wake the computer.

I needed this when i upgraded my motherboard and there was no longer a PS2 connector and my 10 year old keyboard could not be connected to a USB KMV switch. This worked perfectly connecting my keyboard PS2 to USB into KVM and then to my PCs.
