Having your computer detect your fpga as a USB device directly is much too complicated for a beginner.

Use a serial port. Your dev board might already have a serial to USB converter on it. Some boards have a serial connector. For this you will need an external serial to USB cable. If you are using a board with neither, consult with someone about finding c converter that won't damage your board when you connect it to gpio pins. This might be a level shifter followed by an serial to USB converter.
