This is a tool that log the usb data exchange between hardware and device driver!
Like other users, I'm on Windows 7, and stuck on "snpys bridge is not available" (yes, running as admin, which the authors neglected to mention), having followed the instructions in the "readme.txt", which doesn't exist as a file but can inexplicably be accessed from the Help menu. So, for me, this is about as much use as a fishing rod in the Sahara. It's poorly documented, non-functional and unmaintained. Wish I'd read the reviews first.
