Was wondering if theres any way to get the fast charge that you get from the wall charger to work with a usb from computer charge. I know its "slower charge" because the computer also allows data transfer and mounting of the sd card, but maybe theres a possible way to shut that off? Also, would a double USB port cord that are used for external hard drives improve charge time at all? Two normal sized USB coming from computer to the miniUSB port on hero. Thanks!
