PS/2 Compatible Mouse Driver for Windows

PS/2 Compatible Mouse Driver:

The standard PS/2 mouse supports X (right/left) movement and Y (up/down) movement along with three mouse buttons. The mouse reads these inputs at a regular frequency and updates various counters/flags to reflect movement and button states.

The mouse sends these data to the host in the form of a 3-byte movement data packet. It also resets its movement counters when it receives this packet successfully from the host.


A PS/2 keyboard is a type of computer keyboard that was developed in 1987 by IBM. These keyboards are compatible with older PCs, and you can find them in most thrift stores for around $5.

Some PS/2 keyboards have an IR emitter built into them, so they can be used in remote control mode. This is handy if you have other peripherals that need to be controlled.

It can also be useful if you have a laptop with a small screen and need to control it remotely from another computer. It can be a bit annoying to have to connect the keyboard and mouse separately, but it’s worth the effort.

The only issue with hot-swapping keyboards and mice is that if the driver on your host system does not recognize the new device, the devices will not work correctly. This is often due to the difference in the signaling protocol for the two devices.


The PS/2 connector may be a legacy port, but many mice are still compatible with it. Some even ship with a special “PS/2 to USB” adapter that switches protocols depending on which port you attach it to.

This is because the standard PS/2 interface is able to support near-universal compatibility with the BIOS on most motherboards. In addition, it has a lower polling rate than the USB HID interface used by most modern PCs.

Although the PS/2 interface is a bit of a dinosaur, the newer Windows operating systems (Windows 8.1 and up) include USB host controller drivers which should be able to handle most of your mouse and keyboard needs. The best way to find out if your device is compatible with the latest USB driver is to run a quick hardware check using the built-in utility known as Device Manager. The software should then list all the devices that are currently installed on your computer, along with the driver names and version numbers.


The PS/2 Compatible Mouse Driver is a device that allows a USB mouse to operate on a PC with PS/2 ports. Usually, such devices ship with a passive wiring adapter that detects the presence of the PS/2 connector. And then automatically switches protocols accordingly, but they may also use a protocol converter to translate between the two.

Adapters like this one are useful when trying to connect a USB device to an older computer system with PS/2 ports. Such as a KVM switch. This can make it easier to get a newer system to recognize the device. And also to avoid damaging the pins in the keyboard and mouse connectors. Which can be a problem when connecting USB devices to a PS/2 port without an adapter.

These adapters are great for both collectors and professionals looking to protect their traditional PS/2 style investments. They are designed to convert USB keyboards and mice to traditional PS/2 inputs and are easy to install. With color-coded connectors for easy identification.


Drivers are software that allows your computer to read and write to a specific hardware device. This includes USB devices such as keyboards and mice, as well as audio, video, and other components. Some devices require specific drivers for proper operation, while others have generic drivers that work with all Windows versions.

Some mouse devices were designed to operate on both the PS/2 and USB interfaces. Selecting the appropriate protocol at power-on. Typically, such devices were equipped with a USB connector and came with a passive wiring adapter that allowed them to connect to a PS/2 port using the RS-232 or PS/2 protocols.

Some mouse devices also support extensions, allowing for features that are not supported on the standard PS/2 bus. These extensions are usually activated by sending a single byte which is clocked over the PS/2 interface. This byte contains the information necessary to enable the device on the PS/2 bus and report its status back when it moves.
