NIOS II and USB

Hi guys,

I'm trying to use NIOS as a USB device controller. Specifically, I have a DE2-70 board, and a CCD camera plugged into a GPIO board. I've been able to get the pixels and RGB data, and I've even been able to display the frames on a VGA monitor.

What I would really like to do is to implement a USB Video Class (UVC) controller, so that I could connect the development board to my PC via USB. With this, it will be accessible from something like OpenCV or Matlab.

I've been looking through the USB20HR core documentation, but the example doesn't really explain a lot (or maybe I'm just confused). Was wondering if anyone could direct me to any resources like the Altera University tutorials, or any example designs using this particular core? It seems pretty strange that there is so little documentation I could find on implementing a USB device, considering it's a common interface.

Anything at all would be helpful.

Thanks!
