I think you have asked in the OSR list. Sorry but I think this has nothing
to do with libusb-win32 and I am not so sure if the users here can give
any better answer than the driver experts in OSR.

I can only guess that nobody understand your problem there.
Probably you want to explain what you want to do in
more detail.

To me the solution is to forget about usbser.sys and use
USB RNDIS to set up the connection.

Or maybe some CDC-Ethernet based USB class. But if you
need Windows XP support, then USB RNDIS may be the
way to go.
