OSR USB FX2 Linux Driver Overview

One of the classes I took at UCSC Santa Cruz Extension was a Linux kernel class.  I had to do a project for the class so I decided to to learn how to write a Linux USB driver.  I had an interest in learning about the USB protocol for other projects I wanted to do.  I found the OSR USB FX2 development board on the internet and bought one.  It is a board used for learning USB drivers for Windows.  I searched the internet and found a driver that someone wrote for the board but it was based on an older version of Linux and did not compile.  I rebuilt my own driver from scratch based on the USB skeleton file found in the Linux kernel source code.  I was able to get the device working.  I made a presentation for the class which is linked below.
