Controller not working on Windows game version

I know my controller works fine in other games but Phantasy Star Online 2, the controller doesn't work.

Go to the start menu, right-click your profile and choose sign out. Unplug the controller. Plug the controller back in. Sign back into Windows. It should work after this if it is an Xbox controller at least.

Also check to make sure the controller isn't mapped to second player. Happened to me once...

I'm just gonna ask to cover some grounds

What PC do you have some may not by default support controller

What sort of controller are you using

Is it wired or wireless

Is the controller software itself download
