USB on-the-go interface for portable devices

Abstract

The need to connect portable electronic devices to each other has accelerated the adoption of USB on-the-go as an industry standard wired interface. This paper presents an overview of USB on-the-go, and explores some of the applications that this interface enables. Cell phones present a unique challenge to this interface, because of their need to also connect to an analog carkit. The way in which USB on-the-go was adapted to address this requirement is also described.
