@CraigOrangeSoda Thank you so much for this! I couldn't figure it out. Even rebooting the PC wouldn't fix this for me. For some reason I guess unplugging it before signing out and plugging it back in before you sign back in totally fixed it. Its like some kind of black magic.
Its odd too because my old Logitech Gamepad still worked with everything else besides PSO2.
Really appreciate you coming back to your forum post to show the fix you found.
