Adding USB to Serial Support to Davinci EVM Board

Hello friends

I am using Davinci EVM board, for development purpose for a video phone.

I have to add support of plug n play USB netconnect device. Devices which is detected as USb to serial device (/dev/ttyUSB[0-5]) on normal Linux Desktop .

On my Normal desktop i can use wvdial to connect once my device is detected as /dev/ttyUSB*

so to include the support of same to my davinci board, i select the USB serial support and selected generic usb serial drivers, and the remaining drivers, i also included the drivers provided by USB harware vendors.

it compuled successfully and i also update the EVM boards

 

Now when i plug in the USB device is detects as Mass Storage device only and not as USB to serial device.

On my Linux Desktop it detects  as both, Mass storage device and USB serial device, what am i doing wrong on EVM that is it not detected as USB Serial device

 

I also added rule file in /etv/udev/rules directory for same, still no result.

 

Can  anyone suggest what i can do the detect the device as usbserial device?

 

Regards
