Python WMI или winreg, получаем серийный номер USB устройства

Я не смог сделать требуемое средствами WMI, но смог с помощью реестра. Решение рабочее, но сырое, поэтому гарантировать 100% работоспособность я не могу. Если вам известен другой, метод, я с удовольствием его рассмотрю.

У меня нет usb-принтера. Вся информация, которая сейчас будет, мною лично не проверена (имейте совесть, не минусуйте). Поможет, значит поможет, нет, не обессудьте.

Первое - Powershell (из Питон запустить такую команду легко):

Get-PrinterPort | Where-Object { $_.Name -like "*USB*" } | format-list *

Второе - Питон:

import win32com.client

def get_printer_ports():
    wmi = win32com.client.GetObject("winmgmts:")
    for printer in wmi.InstancesOf("Win32_Printer"):
        if "USB" in printer.PortName:
            print(f"Printer: {printer.Name}, Port: {printer.PortName}")

get_printer_ports()
