I am also facing the same issue. I have tried in 3 different computers but no difference at all. No lights are working and it doesn't even show up in usb devices
Is this a new controller? If you aren't seeing the green LED on the side of the device, it might be a firmware issue. You can try running the firmware reset tool available here to see if that helps.
This is not a new device and for that firmware reset tool it needs to be detected via system. Mine is not even detected by the system. So that tool is also of no use. Any other alternative ?
