I broke mine when I hit a power line with my tricopter and I sent it in and they fixed it for free but you don't really need the usb on your gopro you can get live video from the back where the backpacks plug in or you could by a battery backpack which has a usb port on it or just get an external charger I have never herd of a place that will fix gopros I would suggest finding someone that can solder really well if you can't and see if he can fix it
