What is otg-usb?

...R

None of the "little" arduinos support USB Host mode (OTG is "either host or device mode, depending on what you're connected to", essentially.) You might get by with one of the USB Host shields.
MEGA-ADK probably works. Due, Yun, and Galileo, have the HW support, but I don't know the state of software or libraries.

thankx for the info.
helped a lot.
