Product description

This product can easily realize the transmission between PS/2 and USB interface, connect the keyboard and mouse of the USB interface to the PS/2 interface of the host, thus saving the channel for the computer lacking the USB interface.

Specification:
Connector A: USB type A female
Connector B: PS/2 male
Material: metal + plastic
Color: purple / green

Reminder:
1. Some keyboards cannot be used, and there will be compatible keyboards and mice for chip conversion. Some can be used without chip conversion, while others cannot be used! If you've used this adapter, or know your keyboard and mouse have chips, you can buy it!

2. Not all USB mice can be used with this adapter. In fact, only the early USB1.0/1.1 interface can be converted into a PS/2 interface through a converter. If your mouse is USB2.0, we do not recommend you to buy this converter! Due to USB2.0/USB3.0 protocol and functional reasons, it cannot be converted to PS/2 interface. Before buying, check whether your keyboard has a rate of return (125Hz/500Hz/1000Hz) adjustment function, and the USB keyboard keys can be used without conflicts, all of which are USB2.0 interface functions.

Package Included:
4 x PS2 male to USB A female adapter

    Some USB keyboards speak PS/2, but most don't. If yours doesn't (which is most likely), this product won't work. If your keyboard does speak PS/2 however, you shouldn't have any issues.

    5.0 out of 5 stars Problem could be Windows 11 or some else.
    Reviewed in the United States on February 4, 2026
    Verified Purchase
    I'm going to give them 5 stars even though I haven't got them to work yet.
    Could be Windows 11, could be the gaming mouse, it will light up using them, just not move.
    Could be settings need to be changed. I bought them more for a hobby and not a need so I'll come back to them and try them on another computer, different OS, keyboard, and mouse.
    5 stars because they seem to be of good quality, fits pst2 ports and usb port.

    4.0 out of 5 stars Beware of the type of mouse you have.
    Reviewed in the United States on August 4, 2025
    Verified Purchase
    The USB to PS/2 works perfectly with my keyboard, however the one for the mouse, doesn't work. My mouse has a LED light at the bottom that tracks movement. The adapter does not provide any power to the mouse, hence the LED fails to light rendering the mouse inoperable. If you have the old style mouse with the roller ball instead of the LED, then you should be fine.
