Iphone charging...

Hello, my name is Martin
I have a very big problem with a 5v usb boost circuit. When i connect the circuit to the power, the led lights up, but no power... to iphones... everything else works, just not iphones. i already tried shorting the data ports with the 5v pin, AND THAT USED TO WORK, but not now!!!??

PLEASE HELP

I have now tried with adding some resistors to data+ and minus, still nothing

HELP!!!

apparantly the headphones where plugged into the LAPTOP, not the phone, the phone was plugged into a cheap charger and the laptop was pluged into a wall brick also for charging

it is tough to think how the circuit could have ben made unles she was pligging into the laptop and touching metal on it or the headphones had exposed wiring. and she then also picked up the phone will connected to its charger

none of this would explain the burns on her chest of course

I have a photo of the internals of a cheap charger.
They rely on a small piece of foam to stop the phase pin from making contact with the internal circuitry.

I'll dig out the direct link from the investigation ...rather than relay on some reporter.
