How do i see USB_OTG enabled device files in linux-imx?

Hi,

I am using yocto sumo version linux kernel.

I enabled the following OTG configuation in menuconfig:

/********************************************************

Symbol: USB_OTG [=y] x
x Type : boolean x
x Prompt: OTG support x
x Location: x
x -> Device Drivers x
x -> USB support (USB_SUPPORT [=y]) x
x (8) -> Support for Host-side USB (USB [=y]) x
x Defined at drivers/usb/core/Kconfig:44

**********************************************************/

1. What is the device file i can expect in the rootfs with the above change?

2. What are the usb device files needed for communicating with MFG/UUU tool and how do i enable that in the kernel(I see /dev/utp missing)?

Thank you,

Anush D.
