Storage [Q] Moto G OTG fix for CM


until last week's update (Blur_Version.175.44.1.falcon_umts.Retail.en.DE.zi p) USB OTG was not possible with the Moto G. After the update OTG seems to work find on the stock image. Never the less I wan't to bring this correct behavior to my CM Build. I have already tried a lot in the kernel but I am wondering if I am at the wrong place. Do you have any further information what was patched t get this working?

I have looked around in the update but haven't found something.
