[Q] USB OTG + Charging topic

SOCIALIZE IT ⇨

I have a USB OTG Y-Cable but I can't seem to get it to work the way I want. Any help would be greatly appreciated.

I want to connect my Android device to a HiFimeDIY DAC and simultaneously charge my phone (hopefully at a full 1.5A or greater)

I have tried my Galaxy S4 on the ktoonsez kernel. it powers and utilizes the DAC perfectly fine, but the phone doesn't charge. I have tried multiple AC adapters and multiple USB cables - both Samsung branded and otherwise. Do I need to try another kernel? Or another AC adapter or a specific cable? I see there is a patch to enable OTG + Charging on the Nexus 4, do I need to apply a similar patch to my phone?
