My buddy bought a usb hub made for the pro and the usb 3.0 is still the front left usb slot I wanna say the rear should be 3.0 aswell but with my luck lol it's 2.0

Remember this aswell usb slot 1 on your ps is a usb 3.0 slot and the 2nd slot is 2.0

That's weird my friend, my didn't work so I went and disabled it in dayz turned off ps then swapped ports k and m were plugged in to and turned her back on went in game enabled them and boom mouse moved, it's not dayz it's playstation and there usb ports cause i just bought a hub for 4 more slots and I have m and k and my headset plugged in that and external hard drive in the ps4's 2nd usb port and everything works, my usb order on hub is from bottom up starting with headset then keyboard then mouse and they all function but anyways try my potential fix I stated in the beginning and see if it works

The left ports usb 3.0 and the right ports 2.0

Hey bro I got my mouse working, I had the mouse in the right USB port and keyboard in the left so I turned off playstation and swapped ports, m in left key in right and turned on playstation and signed in and started dayz and reenabled m and k and now mouse moves in menus and in game

Tbh lol I had a brain fart typing that out lol its top-left for me aswell imma edit my post

My mouse shows up in the top-right corner but doesn't move what so ever, these 2 issues need to be fixed controllers on dayz are trash.
