Extra pins and USB2.0

I noticed extra pins between the CPU and the switch chip, one is a 10pin and the other is 20pin connector.
What are those for?

Is the USB2.0 port in the Armada 385 exposed?

I think that there is a JTAG connector there, but I will leave the answer for our HW developers.

As for USB 2.0, it is connected to one of the miniPCIe slots. This is because many cards for miniPCIe (such as LTE modems) do not in fact use PCIe signal, but go through USB instead. This way we ensured that these cards will wort in Omnia as well.

The 20 pin connector is a JTAG for the main processor, the second and shorter one is programming interface for STM32 chip.
