Almost perfect On one hand  it is the first of the USB diag apps that I have seen that gives this rather important piece of info: is the device connected in USB 3 or 2? 5-star material right there. On the other  when you tell it to download the vendor info (2.5 MB as it tells you)  it gets stuck on file 2/3 at 3%. And we can't have that  can we? Then after you kill it  it won't start anymore. So -1 star until it is fixed.
