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

success: device 1CE2:0002 opened

error setting config #1: libusb0-dll:error [set_configuration] could not
set config 1: win error: A device att

ached to the system is not functioning.

 

---------------- 2nd run (1.1.14.3 libusb0.sys and libusb0.dll)

C:\projects\apps\libusb-win32-src-1.2.0.0\projects\Release\Win32\testbul
k>testbulk.exe

success: device 1CE2:0002 opened

success: set configuration #1

success: claim_interface #0

error reading:

Done.
