You do not understand USB at all.
USB is a serial bus not a serial line. The bus and its protocol is
invisible to any application. You can only talk to a device.
Building an USB device is nontrivial. You need to learn to program an
USB enabled microcontroller. If your device does not fit one of the
predefined classes with a standard driver then you also need to write a
Windows driver.
