Try to uinstall libusb and install this package: https://sourceforge.net/projects/libusb-win32/files/libusb-win32-snapshots/20100519/libusb-win32-filter-bin-20100519.exe/download. I think you have to install libusb-win32 as a filter driver, otherwise you will have to create an inf file for your device and replace its driver...
