The configuration script check for libusb-1.0 availability first and only if not found check for libusb-0. So if both libraries are installed on the system the build script will use libusb-1.0 It's possible to force compiling with libusb-0 with the --enable-libusb0 switch. If the driver support only libusb0 the script check anly for it.
