Allow S7 to draw >500mA I have a MacBook Pro - as we know, a USB 3 port can output at least 900mA at 5V for 4.5 Watts. 
However, when I plug in my S7, it only draws 500mA. What is the trick to allowing a device to draw 1A? Is it shorting the data pins, or is it a move by Apple to only provide extra current to their own products?

Many Thanks.
Unfortunately the S7 itself comes with USB 2.0 as of official specs, which allows 0.5A max current.
