The traditional parallel port is a 25 "d-sub" connector. Serial ports come in two flavors, either 25 pin "d-sub" or 9 pin. USB (another serial communication standard) is a different animal. PS/2 is also a serial port and it has six pins.
Go to a computer accessories shop and look for the green USB to PS2 Mouse adapter. Or you can buy it online. See the picture at this link (check that the port matches your PC mouse port): http://www.rudyp.com/usbtops2moad.html IMPROVED: Please note the answer above is for converting a USB to PS2 connector, NOT USB to Serial Port. A USB to Serial Port adapter does not, to my knowledge, exist. So please verify if you want a PS/2 (small, round connector) or Serial Port (long, flat connection with many pins) Also, the color of the adapter may vary.
