Re: Reverse-engineering USB protocol

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

if you end up writing your own driver, i would also suggest that you use winusb and have your app implement the protocol and let winusb shuttle the bits for you.

The last one once saved me from writing some Kernel

Maybe this will help you some way,...

OK, I have this device which has no documentation, and black-box software
that doesn't
really work very well. I need to reverse-engineer what is going out
across the USB
connection and/or study ReadFile, WriteFile, and DeviceIoControl calls. I
need to write
working software for this mess. It doesn't do a whole lot: turn on light,
turn off light,
read image. The current software obnoxiously changes the video display
resolution, which
causes all kinds of problems on high-res displays and multimonitor
systems, so I'm trying
to write software that doesn't look like it was written by idiots who
never saw a real
computer or a real GUI.

Any suggestions for tools? I looked at filemon, but it doesn't show the
data going back
and forth, just the IRPs.
