Mouse and keyboard on ps4?

da
- in PlayStation

I bought a mouse and keyboard with an adapter with multiple USB ports. I plugged it in and the ps4 recognizes the mouse and keyboard. The keyboard works in the menu… But the mouse doesn't work and when I go to a game the keyboard doesn't work either. Do I still have to adjust anything? Or can it be because it is not compatible with the ps4? I heard you just have to connect this to usb and then it works… Needs advice

It only works in some games, for example Minecraft and Fortnite

So playing with a mouse and keyboard on ps4 is not possible in every game, but should work in some such as minecraft, but I think it is not possible in ark or gta, for example
