I have also some more informations regarding this OTG detection issue as I have tested same with pre-build package (dtb and zImage) in which Linux version 3.9.0 is used and OTG is working in that image. So, I am sure that there is no any issue from system point of view as I used system image (rbf) is mine and pre-build package images (dtb and zImage) in which OTG is working fine and i am able to enumerate USB device without any issue.

But, When I tested it with my images (dtb and zImage) at that time I am not able to detect any USB device in OTG cable.

So, Please let me know if anyone has any idea to debug or solve this issue and also let me know if any more informations regarding dts or kernel image configuratios required.
