The 3G card connector has a USB host port on the mini-ePCI pins. (It does not use the PCI channels, only uses the USB channel, I would expect them to be on their assigned pins for that interface connector).

The external USB connector is serviced in the Amazon firmware by either the USB mass storage driver or the USB gadget driver.

Getting the USB host driver to work on the OTG port was left as a student exercise by lab126.
