There are several PS/2 mice with an 800/1000 DPI optical sensor, three buttons, and a scroll-wheel. Several modern motherboards have a PS/2 port, such as the MSI Pro B650M-P, ASUS Prime H610M-A, ASRock B450M Steel Legend, GIGABYTE B560M DS3H V2 and ASUS ROG Strix X870E-E.

Do I need extra driver to use PS/2 port computer mouse? Where can I find them? Any reference of interface specification of PS/2?
