hi Podger, thanks for the reply, the hub i use was original from the stock, i never open it. i used it on a CSL ps4 version before I switch to V25 with DH. For X, it is always on A botton no matter CSL ps4 or V25/DH. the issue is that at the first period of time, the button function are the same between CSL ps4 and V25/DH. it just change after a couple minutes of playing. beside this issue, i am quite happy with the DH.
