Razer Atrox dual modding problem

Hello there,

thanks for your attention, and i hope this is the right section to write this post.

i've a problem here. I'm dual modding an Atrox Xbox One arcade stick from Razer with a Hori Mini 4 PCB.
I added a neutrik USB adapter to have one cable for each pcb.
Now, both pcbs are common ground, so i use the classic commond ground wiring to connect ground and signals.
But, when i connect the usb or the atrox cable, buttons work well but the stick is not working. every direction i push is wrong, only UP is right.
I tried EVERYTHING.
Could you help me to find the problem please?
Thanks,

Mast
