Abstract:
A method and apparatus for transferring data from a first electronic device to a second electronic device, both first and second electronic devices having Universal Serial Bus (USB) client interfaces, the method comprising the steps: connecting the two electronic devices with a USB cable; toggling the voltage on a VBUS line of the USB cable between logic high voltage and no voltage at the first electronic device; detecting toggles of the VBUS line at the second electronic device; and interpreting the toggles detected in the detecting step as data.
