Hello, I have recently brought a USB 3 PCI Card for my pc, as I was told it would charge my iPad 3 via PC. This is the link to the product ... http://www.amazon.co.uk/gp/product/B005LV3Z0A/ref=oh_details_o04_s00_i00? ie=UTF8&psc=1 . The ipad doesn't charge after installing drivers that came supplied. I have tried to see what power is being sent when its plugged in via device manager. But this is all I can see ... ... I am stuck from here ...many thanks, Stuart P.S. this PCI card DOES have a power source going to it, attached from the PC's power unit.
