Not so sure. I still think this has nothing to do with libusbK.

You see that libusb needs to claim Interface 0 in order to claim Interface 1.

Please use Zadig to reinstall driver to use WinUSB as the parent driver
of the USB Composite Device, I bet the problem will go away.

Or you can delete libusbK.dll from your system to see if the issue
is still there or not. If it does not exist, then it points problem to
libsubK.dll. If it still exist, then it is not a libusbK.dll problem.
