I've searched and can't find it. Where are the 6 USB locations? Are any of them in the 3rd row?

All the answers you seek are here (yes, two in the third row, same side):

Now, keep in mind that what that answers isn't the next question: "where are the optional 2 additional in the 8-USB port versions?". Speculation is they're also in the third row, other side though.

The additional USB ports are installed on the left side of the third row between the speaker and the seatbelt retainer. If you inspect that area you’ll find the installation drill points molded into the side panel. They draw power from the light in the trunk.
