In order to use libusb/libftdi under Windows you have to install the supported driver like WinUSB, you can not use the FTDI vendor driver. https://github.com/libusb/libusb/wiki/Windows#Driver_Installation I believe your Windows 7 machine has the WinUSB driver installed. You can use Zadig to switch the driver. https://zadig.akeo.ie/ -- Xiaofan -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details.
