I got it to connect an ancient Microsoft Natural keyboard with a PS/2 port, I connected it to the USB 2.0 port of the computer and it works just fine, even the multimedia keys, calculator, etc! Impressive! I thought I would throw the keyboard away (immortal, I don't even remember when I bought it, made in Ireland, just think about it...) but with this cable, it continues unabated. If you have similar needs, buy it with your eyes closed!

It does what it says on an old IBM and Microsoft keyboard as well as an old HP mouse... the mouse with a scroll wheel is not worth it but the old keyboards are far superior in quality to the current ones.

I used it 2-3 times and everything was fine. No disconnections, no crashes, no other strange surprises

It is not a passive adapter, it worked where other cables had failed. It appears in the operating system as an HID device and the relevant drivers are installed.

I put it in an old keyboard (PS/2) that didn't work with similar conversion plugs (from one USB to the other female PS/2). It works great... I will try a mouse as well to see if they work simultaneously. Definitely value for money!!

It works perfectly for connecting old PS/2 type to USB. Tested on desktop and laptop. Be careful, if the keyboard has a POWER button, it will not work for starting up the computer.

I connected it (I only put the keyboard). It made that satisfying click that gives so much pleasure to our brain and it works just fine. It's not a complex product. It has a job to do and it does it well. You don't want anything more than an adapter.

For now, it works fine. It was tested on the Logitech Internet 350 keyboard. I have tried 4 different adapters for this specific keyboard and only this one worked. The test was conducted on 2 different computers:
1) on a desktop computer with Windows 7 (ASRock H61M motherboard)
2) on a laptop computer with Windows 10 (ACER EXTENSA 2540-51H1 NOTEBOOK)
On the computer with Windows 7, the first time I had to load Windows first and then connect the keyboard.

It worked on a Microsoft keyboard and what impressed me and I didn't expect was that the auxiliary keys (forward, back, home, etc.) also worked.

Very satisfied. It worked fine on win10/64 with a Compaq keyboard and a Microsoft trackball mouse, both connected simultaneously. (Another wireless one, which I bought a few days earlier, wasn't recognized at all)
It is recognized by the post so it works in the bios as well. At first, Windows recognized the keyboard as a barcode scanner but it still worked. This was later fixed. One star is missing because a few times, right after starting Windows, the USB needs to be unplugged and plugged back in for it to be recognized. This, as well as the previous issue, might be due to the keyboard being very old.

Purchased on 17/10/2018, broke today on 21/12/2018 and went crazy (the keyboard lights were flashing)!
While it was working, the multimedia keys on the Microsoft PS/2 keyboard were not functioning, but that didn't bother me. Yes, I also tried another identical keyboard, and it had the same issue.
Help us. I only paid 1.66 euros for it. Of course, I won't bother with it anymore!

It worked great with the Microsoft Multimedia Keyboard 1.0A. Only the multimedia keys didn't work (My Documents, My Pictures, etc), but that didn't bother me at all.
