Works with my HanaHo HotRod SE

Pros: Works perfectly with my HanaHo HotRod SE Control Panel. Where I once needed a PS2 input on my PC I now use a USB. This is good because my PC does not have a PS2 input and most new PCs do not. It made a great non-usable product usable again. :)

Works for me

Pros: Along with an AT to PS/2 converter I was able to connect an old Kinesis keyboard into a USB port.

Cons: If your PC has closely spaced USB ports it may block neighboring ports because of its size.

Other: Today's keyboards are just awful. I have IBM (PS/2) and Kinesis (AT) keyboards from the '90s that I wanted to keep using. However, they won't work with my newest PC, which has USB inputs. I was told that I needed an active PS/2 to USB converter, not a passive converter. I tried other "active" converters with no success. This one works.

Works as advertised for older PS/2 keyboards

Works out of the box for an older mechanical keyboard with PS/2 connector. I use this adapter with both a Mac and a Linux box without issues.

totally worth it

I had several custom PS2 keyboards for a specific application that a client wanted to use on some newer Dell workstations. The workstations had PS2 ports, but the keyboards weren't recognized. After some googling, it became clear that it was a Windows OS issue. I lost a day and a half troubleshooting and fighting with the OS when I found these. Plugged them in and voila - problem solved!

It works. I am using it to connect a very old AT keyboard to USB (with my old AT to PS2 adapter.) Most PS2 to USB adapters I have tried won't work with the other PS2 to USB adapters I have bought This adapter works! I can keep using my specialized AT style keyboard.

While this is specifically designed for a mouse or keyboard, we have had customers get these to work with Scanners and other PS/2 devices.
