Have your tried to use the latest version of libusb (libusb-1.0.dll)
from libusb project (1.0.19 version)?
    http://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.19/
    Windows binary is libusb-1.0.19.7z

The ST-Link v2 is shipped with WinUSB driver so it should work
without changing to the Zadig driver. The Zadig generated driver
will be a bit different from the ST WinUSB driver. Both should
work with libusb/OpenOCD.
