Do you mean that libusbx is failing to interact with ceusbkwrapper? As 
well as ceusbkwrapperdrv.dll, have you included the ceusbkwrapper 
user-space library (ceusbkwrapper.dll) in your image? This is used by 
libusbx to communicate with ceusbkwrapperdrv.dll. When you run libusbx 
with logging enabled, do you see either of the following messages being 
logged:

could not resolve DLL functions

could not connect to driver

I'm not aware of any support provided by libusbx for the USB Device 
Firmware Upgrade device class.
