How to interface USB to SPI communication in Windows.?

I have a usb to spi converter. I have attached it to windows 10 machine and need to work on this. I have connected this to omron thermal sensor which works on SPI and because windows doesnt have any spi, thus I have used usb to spi converter. The converter's manufacturer is FTDI.

If I open device manager, I do not see any COM port taken this converter. I can only see USB to Serial Converter showing under USB:

enter image description here

My plan was to use this python library usb-iss but because it doesn't have any COM port, I am not sure how can I start fetching data from this converter. Can anyone please help and suggest some good soultions. Thanks

Then you bought the wrong hardware. The usb-iss module requires usb-iss hardware based on a microchip pic µC.

For FTDI hardware one would use ftd2xx or LibFTDI - there are pyhton wrappers for these (ftd2xx, pylibftdi). The ftd2xx library uses FTDI drivers, while LibFTDI uses LibUSB drivers.
