  1. Raytheon Senior Project Jarret Allen, Luis Cintron, Michael Kubacki, Robert Skinner Department of Computer Science and Engineering University of South Florida Tampa, FL 33620 jjallen3@cse.usf.edu lcintron@mail.usf.edu mkubacki@mail.usf.edu ras1@mail.usf.edu pres_dr.ppt

  2. Acknowledgments • Jeremiah Schroder and Michael Stillo – Raytheon • Project supervision and support • Tara Mazzocco – Future Technology Devices Int. • Hard work to acquire a free hardware sample for our group • Bob Recny – Future Technology Devices Int. • Quick feedback and engineering advice on the feasibility of hardware implementation using Vinculum-II products

  3. Agenda • Background • Problem • Requirements • Design / Specification • Analysis • Project Plan

  4. Background As of today, an average smart phone user cannot transfer files directly from a USB Mass Storage Device to their phone.

  5. Problem Since smart phones are "slaves," they require a USB host controller to communicate with a USB mass storage device. Host is Needed! X Slave Device Slave Device
