I think this has been posted before but I didn't see it, so I thought I'd post it up in case anyone needs it.  You can buy the following USB to RS232 FTDI pigtail for around $25.  Then all you need is a diode, 10k resistor and wire it up just like a regular old serial logging cable. You only need to use the yellow, orange and black wires from the USB cable, I've attached a diagram that shows you how to wire it up according to the color of the wire.  Once I installed the drivers, I went into the device manager and assigned the USB to serial adapter to COM port 1, that way when I launch WW, the data logger is ready to connect on COM1.
