i need to write data to a usb port, but i dont know how. Are there any API provided in windows that will help me do so, or will i have to write assembly?

You don't write to a port, you write to a device.

Are you going to write to the host from a USB device or to the USB device from the host?
I assume you want to write to a USB device from the host.
Try jungo win driver at www.jungo.com
