  --- BEGIN ISSUE ---
  Find USB device from hardware information
  The COM port of virtual Com ports via USB may change from time to time.
  I propose a simple helper method, which retrieves the COM port of a USB virtual port according to hardware information (vendor id, product id, serial number).
  This method allows to specify the hardware information and then to connect always to the correct device, independent of the COM port number assigned at that time.
  
  Rough idea:
  
  ~~~python
  from serial.tools import list_ports
  
  def findPort(vid: int, pid: int, sn: str) -> str:
      """Find the port name ('COM5') of the first device with the given USB information.
  
      :param int vid: Vendor ID.
      :param int pid: Product ID.
      :param str sn: Serial number.
      :return: Port as a string as `device` attribute returned from `list_ports.comports`.
      """
      for port in sorted(list_ports.comports()):
          if port.vid == vid and port.pid == pid and port.serial_number == str(sn):
              return port.device
      raise AttributeError("No device found for the given data.")
  ~~~
