Kodi can't support controller? bug?

[gabriel-ng]

Hi I notice something weird as this is my first time using Recalbox .. I'm on 4.0 at the moment. When I launch Kodi with my PS4 controller plugged in to the USB.. it shows the splash screen and then kick me back to ES. But if i do it again but unplug the controller.. it will load successfully into Kodi. Some kind of controller bug?
