Unable to write in control module register USB0_CTRL OTGVDET_EN bit /phy is not enable (MUSB as Device)

I am using linux 3.8.13+

Board Beaglebone Black

writing Musb device drive (type B)

>>>I am compiling my driver Separately, For that in Linux Kernel

>>i commented driver/usb/Kconfig file #source "drivers/usb/musb/Kconfig"

>> and in driver/usb/Makefile #obj-$(CONFIG_USB_MUSB_HDRC)    += musb/

#clock configuratiion/enabling the clock in the smart mode    

INITIALIZATION  of Registers is as follows

unable to write in control module register and interrupt is not getting generate.

please any one can help me to resolve this problem,
