Hi krasnejv:
No, I don't.
I think the actual driver that the Atmega16u2 is tied to is one of the libusb0.sys files in the \arduino\drivers directory. (see attached photo)
However, what I don't know is exactly which one Windows may have used since it is in three different sub folders (amd64, ia64 and x86...unless they are all the same) Since I have a 64-bit installation for windows, I haven't confirmed whether or not those libusb0.sys are the same as they are in different folders based on 32-bit and 64-bit installs.
Other than having to do a clean install of windows or other complex workarounds, it seems VERY unfortunate to have to do for such a small device. I'm not there yet...I haven't given up. I've been working on this pretty much all day today...as I just received my new kit yesterday evening.
