Please don't set LIBUSB_DEBUG. You are actually reducing the debug level 
by doing so. The -d option alone will set the debug level to maximum, 
and provide the information we need. Can you please try again without 
LIBUSB_DEBUG. You should get something similar to what I post below.

Great. I have a 18F2550 device with the libusbdotnet firmware (might be 
an older version though). I reinstalled the WinUSB driver using the 
latest Zadig and I don't have an issue. Below is what I get, and the 
type of debug output I would like to get from you:
