I want to know the answer to the following question:
When was the USB Battery Charging Specification Revision 1.1 released?
All the background I'm provided with is that "Contrary to the standard downstream port, for which current draw by a connected portable device can exceed 100 mA only after digital negotiation with the host or hub, a charging port can supply currents between 500 mA and 1.5 A without the digital negotiation.". Is that enough to answer the question?
