AIM:
Our aim is to implement the driver for the USB devices.
INTRODUCTION
A device driver is a computer program or software which communicates with the hardware devices. The hardware devices include flash disk, mobile phones (through data cable), printers, mouse etc driver typically communicates with the device through the computer bus or communications subsystem to which the hardware connects. Drivers are hardware-dependent and operating system specific. A device driver simplifies programming by acting as a translator between a hardware device and the applications or operating systems that use it.
TECHNICAL ASPECTS
• Libusb library (that allows communicating with the external devices) is used.
• Program coding is done in ‘C’ language.
• Operating system used is Linux Fedora 13.
• External devices attached during testing……..
> Flash disk (Pen drive)
> Mobile phones
> USB Mouse
Software Development Life Cycle (SDLC)
The model used in developing this software is build and fix model.
• BUILD AND FIX MODEL
It is a simple two phase model. The first phase is to write the code and the next phase is to fix it .Fixing in this context may be error correction or addition of further functionality.
