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.
