Usage for the Mini-USB 2.0 OTG port?

Hello, we could not find much detail about the usage of the Mini-USB 2.0 OTG port with the JeVois-Pro, except that it should be working both in host and in device modes. Could you provide examples of usage for each mode? For example: can it be used to power the device? can the JeVois-Pro be used as a Web or UVC camera in device mode? Any other interesting usage we may be missing??? Thank you.
