Help making OTG cable with power (solved)

Hi

Iv'e tried a lot of the guides on how to make the OTG cable with power but I can't get it to work.


What I tried:

The OTG cable I have from before, but I need it to deliver power.
Every thing works with no power connected, but as soon as i apply power it wont work.

I've been trying to cut the cable in the middle only the red and the black wire, and than ad power to those cables from an usb adapter but as soon as I add power the OTG stops working, and my nexus is not charging.

Iv'e tried adding double the power, cut the black and red wire in the OTG cable, than add 2 USB adapters one sending power to the female USB and one sending power to the micro USB for the Nexus, still nothing.

Tried adding power to black going to both devices and red only to nexus, still nothing.

What am I doing wrong?

Are you using a kernel that supports USB OTG charging? To get mine to charge I have to plug the power into the OTG cable and then plug it into my device.

I found the problem.
The people making the OTG cable have had some fun and used white cable for power and red for data, no wounder I couldn't get it to work
