Thanks for all the information. I was initially confused between writing
a driver for Linux and writing a program to download the images. The
latter is what I want. I used USB snoop to capture the data and there's a
whole lot of it which I am slowly going through. Gerald has a good site
which list his progress on the chipset. If I end up getting something to
work, I'll post it here. Thanks again.
