INTRODUCTION
1.1 Introduction
The first version of the Universal Serial Bus (USB) specification was released in January 1996.In April 2000 , version 2.0 of the USB specification which supports transfer rates upto 480 Mbps , was released. Because of its low cost, high data-transfer rate, ease of use and flexibility, USB has gained wide acceptance in the computer industry. Today , many peripherals and devices connect to computers through USB interfaces. Currently most general purpose operating systems provide support for USB devices, and it is relatively easy to develop applications in C that access such peripherals. Linux operating system do not provide remote access through USB between different machines .Here we utilize its high bandwidth to transfer files between machines using USB without using any network cables.
1.2 Objectives
The USB remote file access allows high speed transferring of files between two machines.

1.4 Advantages Of Using USB Cable for Remote Access
• Transfer files between two PCs (or three PCs using two cables)
• Fully compliant with USB 1.1 and USB 2.0
• USB 2.0 High-speed performance with data transfer rate of over 15 Mbps
• No external power needed (Bus powered from either USB port)
• Low power consumption
• Supports suspend and resume for power management
• Supports remote wake-up
• Terrific for laptop/notebook to desktop file transfers.
1.5 Module Overview
This project mainly contain two parts 1.Kernel Module (USB driver) 2.User Interface
1. Kernel Module
In this module we create a device driver for USB direct link cable which is used to connect between two systems. The driver is designed in such a way that it should be efficient and simple to the Linux operating system. The files are transmitted using file transmission protocol. The low level system call and device accessing will provide reliable, efficient, fast transferring of files between machines.

2. User Interface
After the kernel driver became a part of the operating system user can use this for remote access. An interactive user interface will provide smooth and transparent front end to the user. We implement client server architecture in user side program.

REVIEW OF LITERATURE
2.1 Literature Survey
We have went through several Linux Kernel Projects like firewalls and device driver programs to get an overview about how we can alter the kernel at system level.
As a reference to our project we constantly went through the site www.linfo.org [5] to understand the power of C in system level programming .Also Linux Driver Programming by Jonathan Corbet, Alessandro Rubini, Greg Kroah- hartman [6] and Linux Hardware Device Driver by Andrew O’Shauqhnessy [7] helped to learn about device driver programming in Linux.
During the initial phases and for the purpose of documentation we referred the Wikepedia sites and for getting an overview of various software development stages , also the Pankaj Jalote’s Integrated Approach to Software Engineering was also a good reference from student’s point of view.
The technical details , advantages figures and features of a USB direct link cable has been collected from sites like www.usbfirewire.com [1] and www.hardwaresecrets.com [4].
The basic understanding about Linux kernel and its functions are made possible through an article “Antomy of Linux Kernel” provided by www.ibm.com.
