PS1 controller + usb adapter working in unreal 4, how?

Hey there,

So I am recreating a PS1 game, and I have a pre duel-shock controller here with a usb adapter. I plug it in and it installs a driver, but as far as I know it doesn’t work out of the box. Is there any sort of optional driver I need to install or any sort of documentation I can be directed to?

Thanks,
