(if i need another cable can someone please tell me wich becuse i didnt find)

so when i connect the cable to the phone nothing happened eaven if the phone off or on or i powerd on when he connected.

and when i start china editor i didnt get something that show me that the phone connected (i dont know if i need to see something about this)
