OMAPL138B-EP: failure of detection of voltage on vbus line of usb

Part Number:OMAPL138B-EP

Hi,

I was implementing USB CDC on omapl138 using starterware from TI as the reference. But the device is not even recognized as an unknown device by the PC. I observed that USB0VBUSSENSE bit is not set when usb cable is connected. There was a valid 5V on the vbus line(the same cable works well with other devices). What could be the reason behind this issue?

Any help would be appreciated.
