Dear All,
I have just started (few months back) working in the field of windows device driver.
I m in the process of developing a software based USB Protocol Analyzer.
My idea to develop is to create a filter driver and place it below hub driver as lower Filter but I am not sure will it work or not. and will it trace all the USB setup pkt or not.
Anybody would like to comment on this.
Any help would be highly appreciated.
Thanks

And do you understand that there are several very good products that do
this already, including some that are free?

Well, it will work in the sense that you can catch all of the URBs.
However, URBs are all you get. No software sniffer can actually see the
USB packets going out on the wire, nor monitor the enumeration process,
nor catch the packet timing. As long as you understand your
limitations, the project can be done.
