Pratibha,

If your kernel configuration has the USB CDC serial driver you can open and
communicate with the USB ports like /dev/ttyUSB0.

It depends on what kind of device driver your AT91SAM9260 is using. You
should get usb interface information by lsusb -v command after you plug in
your device, then see which driver is suitable for you.
