keyboard: Rosewill RK-9000V2 -- the keyboard comes with a USB connector and a ps/2 connector
motherboard: MSI Z170A GAMING M3 ATX LGA1151

I thought the ps/2 connector was more integrated with the system than the USB connector. The USB connector even worked when getting into the BIOS settings at startup.

Do I need to install the motherboard drivers for the ps/2 connector to work?
