I'm looking for another set of USB 2.0 pins for an internal card reader. The unit I'm looking at has 3.0 for the readers and 2.0 for the ports. The Rampage manual only shows one set of USB1314 pins, another that can be used for either USB 2.0 or ROG and I see another 2 sets of 8 pins right above it with the markings USB 1112. The other USB 2.0 have 9 Pins. These pins are not identified in the manual and I would like to confirm what they are before I plug anything onto them.
