持續監控USB連線狀態

我遇到了 USB 連接埠問題。當我將行動裝置連接到 PC USB 連接埠時，有時會斷開連接並立即連接。所以我想持續監控USB連線狀態。有什麼方法可以即時監控連線狀態嗎？

如果能取得只有 USB 連線狀態的日誌檔就好了

您可以使用pyudevpython 腳本來監視 USB 連接、將事件記錄到檔案並將事件列印到控制台。

首先安裝包pip install pyudev

那麼這是腳本：

import os
import sys
import pyudev

from datetime import datetime

def log_event(event_type, device):
    timestamp = datetime.now().strftime("%Y-%m-%d %H:%M:%S")
    message = f"{timestamp} - {event_type}: {device.get('ID_SERIAL_SHORT') or device.get('ID_SERIAL')} - {device.get('ID_MODEL')}"

    with open("usb_connection_log.txt", "a") as log_file:
        log_file.write(message + "\n")

    print(message)

def monitor_usb_events():
    context = pyudev.Context()
    monitor = pyudev.Monitor.from_netlink(context)
    monitor.filter_by(subsystem='usb')

    for action, device in monitor:
        if action == 'add' and 'ID_SERIAL' in device:
            log_event("Connected", device)
        elif action == 'remove' and 'ID_SERIAL' in device:
            log_event("Disconnected", device)

if __name__ == "__main__":
    try:
        monitor_usb_events()
    except KeyboardInterrupt:
        print("\nMonitoring stopped.")
        sys.exit(0)
