Novel multi-interface USB prototype device for merging commonly used peripheral devices

28 May 2015-pp 17-22
TL;DR: The aim of the paper is to introduce a novel concept to combine some commonly used USB classes in a single device to create a composite device that functions in multiple ways.
Abstract: The Universal Serial Bus (USB) Specification allows combination of different USB components into a single device. This creates a composite device and each component is recognized as an independent device. The aim of the paper is to introduce a novel concept to combine some commonly used USB classes in a single device to create a composite device that functions in multiple ways. The paper shows some ways of combining two different USB classes using available Real Time Operating System (RTOS). The paper explains the implementation of USB Human Interface Device class and USB Mass Storage Device the classes used in the two most commonly used peripheral devices, using available stack libraries and clearly explains the important aspects in implementing the said classes. The prototype device mentioned will function both as a pointing device and a storage device.
