Default [Q] [CLONE] HDC Galaxy S5 G900H 1:1 MTK6592 OctaCore 1.7GHz

I am trying to get my HDC Galaxy S5's split OTG cable to charge the phone at the same time - Somewhere in the XDA forums I had read that something in the kernel had to be modified for this function to work... I can't find where I read that! Is there someone knowledgeable on this subject who has had success in getting the OTG cables to "Charge" their phone at the same time?
