My quest for USB connectivity continues. Looking at the USB board diagram on the wiki http://gumstix.net/wiki/index.php?title=USB, I am assuming that the voltage regulator must be installed between the USB connector and pin 20.  Is this correct?  I want to use the TI TPS73133 non-cap voltage regulator http://www.ti.com/lit/gpn/tps73133.  Please see updated board illustration at http://www.zeletron.com/gallery/uploads/modified_24pin_to_USB_board.png.  Will this work or am I doing something wrong?  I know it's not shown on the diagram, but Pins 17 and 18 obviously need to be connected to the USB connector.  So which pin on the USB connector correlates with pin 17 when looking at the picture, top or bottom?
 
Thanks,
