Notes on Getting Python to Talk to FTDI FT232 chipset for USB Serial Communication

NOTE: This is incomplete and is nothing more than just notes for myself. It is not yet part of a complete solution and I don't fully understand all the consequences that may be involved. Follow at your own risk.

To get python to talk to FTDI FT232 chip for USB Serial Communication (Windows)

Replace the existing FTDI Driver with libusb-win32 using Zadig (Reference) 

Now the device shows up when searched for using VID and PID:

import usb

import usb.util

print(usb.core.find(idVendor=0x0403, idProduct=0x6001))

It WILL NO LONGER list under:

import serial.tools.list_ports

# List all available COM ports

ports = list(serial.tools.list_ports.comports())

# Print information for each port that is currently in use

for port in ports:

    if port.pid is not None and port.vid is not None:

        print(f"Port: {port.device} - VID: {hex(port.vid)} - PID: {hex(port.pid)} - Description: {port.description}")

but now pyftdi can now connect using VID and PID:

import time

from pyftdi.ftdi import Ftdi, FtdiError

try:

    ftdi = Ftdi()

    ftdi.open(vendor=0x403, product=0x6001)

    while ftdi.is_connected:

        try:

            ftdi.poll_modem_status()

            status = ftdi.modem_status()

            print(status)

        except FtdiError:

            break

        time.sleep(0.1)

finally:

    ftdi.close()
