how we can send data to USB port

That is not possible. USB consists of a controller device, and devices plugged into it. Only the controller can directly access any particular physical connector. How to send data to a device connected by USB depends on what class of device the plugged-in device tells the USB controller it is.

You cannot send data to a USB port. The USB controller does not allow it. The port is under the complete control of the controller.

I suspect that what you want to do is send data to a virtual serial port that is connected by USB. If so then you use serial() to designate the name of the USB port you want to work with, and you use fopen() on the virtual serial port, and then you use fprintf() or fwrite() to send data to the virtual serial port.
