MiniPCIe specification includes both PCIe _and_ USB2.0 signals (on pins 36&38) (and also SMBus, SIM and LEDs drivers check the following table for details http://pinoutsguide.com/Slots/mini_pcie_pinout.shtml ) so the possibility to have a USB port connected to the MiniPCIe on the AX3-4 makes sense. For example most 3G MiniPCIe boards are using the USB2.0 signals and not the PCIe ones.
