So far after a lot of test runs, I realize that my device works only
works with 1.1.14.3 and never works under 1.2.0.0
I ran the testbulk.exe provided from the libusb-win32 sources with
modifications in the code to match with my device VID, PID, and
endpoints. The first run is with 1.2.0.0. I then swapped the libusb0.sys
and libusb0.dll files to version 1.1.14.3 You can see the setting
configuration was successful on the 2nd run.
----------------- 1st run (1.2.0.0 libusb0.sys and libusb0.dll)
C:\projects\apps\libusb-win32-src-1.2.0.0\projects\Release\Win32\testbul
k>testbulk.exe
