I managed to break the usb port on the side of my controller.So I replaced the daughterboard.
works fine with the cable to the phone but as soon as I plug it into anything else (I have tried multiple cables which work with the other controller) it will turn off and then will not turn back on until the battery has been disconnected and then reconnected.
Maybe somthing got shorted when the usb port broke initially?
wondering if anyone else has had this issue?
I have another controller so am going to start swapping parts out to locate the issue but wanted to check here first.
Many Thanks.
