I want to know the answer to the following question:
When was USB Battery Charging Specification Revision 1.2 released?
All the background I'm provided with is that "On the other hand, several changes are made and limits are increasing including allowing 1.5 A on charging downstream ports for unconfigured devices, allowing high speed communication while having a current up to 1.5 A, and allowing a maximum current of 5 A. Also, revision 1.2 removes support for USB ports type detection via resistive detection mechanisms.". Is that enough to answer the question?
