Pyserial获取COM端口后面的设备名称

Question

我想获得连接到COM端口的设备列表。例如，我没有输出python -m serial.tools.list_ports的COM1 COM2，而是希望得到像Arduino_Uno Arduino Due等的输出（例如，像Arduino Gui那样做）。

我找到了一些列出COM端口的答案（如Listing available com ports with Python），但我的问题没有答案。

@J.P。彼得森是对的 - 串口本身并不提供这些信息。但USB规范允许一些信息被偷偷进入，而且serial.tools.list_ports.comports（）值得回报。以下代码剪切来自我的ArduinoBase类，该类在Windows和Linux下运行，并且可以满足您的要求，即它可以为您提供Arduino Uno和Arduino Due描述。

def listPorts():
    """!
    @brief Provide a list of names of serial ports that can be opened as well as a
    a list of Arduino models.
    @return A tuple of the port list and a corresponding list of device descriptions
    """

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

    resultPorts = []
    descriptions = []
    for port in ports:
        if not port.description.startswith( "Arduino" ):
            # correct for the somewhat questionable design choice for the USB
            # description of the Arduino Uno
            if port.manufacturer is not None:
                if port.manufacturer.startswith( "Arduino" ) and \
                   port.device.endswith( port.description ):
                    port.description = "Arduino Uno"
                else:
                    continue
            else:
                continue
        if port.device:
            resultPorts.append( port.device )
            rdescriptions.append( str( port.description ) )

    return (resultPorts, descriptions)
