我如何在Python中用Linux监听'usb device inserted'事件？

pip install pyudev

import pyudev

context = pyudev.Context()
monitor = pyudev.Monitor.from_netlink(context)
monitor.filter_by(subsystem='usb')
monitor.start()

for device in context.list_devices(subsystem='usb'):
    print('USB device connected:', device.sys_path)

while True:
    device = monitor.poll(timeout=1)
    if device:
        print('USB device connected:', device.sys_path)
