I was laying out a serial arduino that would use a USB connector for power, and the
layout I came up with from "first principles" wasn't matching the layout of the USB
connector in the downloadable CAD files of the USB arduino (arduino_usb_8.)
Further looking around shows that the online schematic for NG has the pins wired
exactly backwards from usb_8 (the ng schematics match my pinout understanding.)
Did you wind up with some odd USB connectors or what?
Just as an update, this was wrong, but it's been fixed in the USB V2.1 cad files
