They just then plug into the USB port on the device. Remember you may need an adapter if the male and female USB plugs are not the same type.

Are cellphone USB ports ubiquitously "OTG"? Otherwise a gotcha would be buying a phone that only had a slave port, so it can plug into a computer, but you can't plug devices into it. http://en.wikipedia.org/wiki/USB_On-The-Go Hm, from reading that, it sounds like OTG is implemented by the OS (like a WPA supplicant) and has no physical component other han a stock USB port.
