Retrieve list of USB items using Python

Question

How can I retrieve the items plugged into the computer through USB using python? I've searched around on here and found some old examples which don't appear to work anymore as they are over 5 years old.

I would like an example where I can list the names seen in the image below which is a screenshot of the Device Manager.

The code below lists all the USB devices but none of the data returns the Names seen in the image, why is that?

import win32com.client
import pprint

wmi = win32com.client.GetObject ("winmgmts:")
for usb in wmi.InstancesOf ("Win32_USBHub"):
    # print usb.DeviceID
    # pprint.pprint (dir(usb))
    # pprint.pprint (vars(usb))
    # print usb.__dict__
    print ('Device ID:', usb.DeviceID)
    print ('Name:', usb.name)
    print ('System Name:', usb.SystemName)
    print ('Caption:', usb.Caption)
    print ('Caption:', usb.Caption)
    print ('ClassCode:', usb.ClassCode)
    print ('CreationClassName:', usb.CreationClassName)
    print ('CurrentConfigValue:', usb.CurrentConfigValue)
    print ('Description:', usb.Description)
    print ('PNPDeviceID:', usb.PNPDeviceID)
    print ('Status:', usb.Status)
    print ('\n')

Could you show what your code gets for one of the entries? I would not be surprised if the nice labels were part of Windows Explorer... Windows philosophy is that an end user should not deal with system data. — Serge Ballesta

I didn't know Python can consume WMI. There may be some WMI API that you can use for this, that returns something like what you see in the Device Manager — ashes999

Your title asks about USB, but the text of your comment seems to imply you are interested in COM devices only. Are you interested in ALL USB connections, or just the Serial ports? — RufusVS

I would install pyserial

py -m pip install pyserial

and use serial.tools.list_ports. You can execute it as a module:

py -m serial.tools.list_ports

or incorporate the module and its corresponding methods into your code base:

import serial
from serial.tools import list_ports

if __name__ == "__main__":
    for port in list_ports.comports():
        if "USB" in port.hwid:
            print(f"Name: {port.name}")
            print(f"Description: {port.description}")
            print(f"Location: {port.location}")
            print(f"Product: {port.product}")
            print(f"Manufacturer: {port.manufacturer}")
            print(f"ID: {port.pid}")

Your code will enumerate USB COM ports but the OP question title asks about all USB devices, though the text screenshot only shows COM ports from the device manager. I think the title should be more specific if only COM ports are wanted. In that case, you answer is perfect.
