No, that's not correct. Both ports are USB2.0, but the fullsize port (the host port, USB A connector) is HS (High Speed) only, it cannot support the other two (lower) speeds. On the other hand it can provide 500mA. The small-connector OTG port (USB mini-AB) is also USB2.0, but it can support all three speeds. It can also be configured to be host port. But this port cannot provide more than 100mA. Edit: Found a link that describes it better than I can: http://pandorawiki.org/USB_reference
