如何使用python检测USB设备是否插入？

Question

我想创建一个脚本来检测 USB 驱动器插入计算机后的情况，现在只是在 cmd detector中打印。

注意：我在搜索后使用的是 Windows，我发现我需要使用pyudev 包才能与串行端口通信，并且我需要知道 USB 设备的供应商 ID。

我尝试编写以下代码：

import pyudev
context = pyudev.Context()
monitor = Monitor.from_netlink()
# For USB devices
monitor.filter_by(subsystem='usb')
# OR specifically for most USB serial devices
monitor.filter_by(subsystem='tty')
for action, device in monitor:
    vendor_id = device.get('ID_VENDOR_ID')

    if vendor_id in ['USB\\VID_0930&PID_6544&REV_0100'] or vendor_id in ['USB\\VID_0930&PID_6544']:
        print ('Detected {0} for device with vendor ID {1}'.format(action, vendor_id))

但系统崩溃并显示此错误：

import fcntl ModuleNotFoundError: No module named 'fcntl'

我认为 fcntl 仅适用于 Ubuntu，因为我尝试安装该软件包但它不存在。

试试这个

import win32file
def locate_usb():
    drive_list = []
    drivebits = win32file.GetLogicalDrives()
    for d in range(1, 26):
        mask = 1 << d
        if drivebits & mask:
            # here if the drive is at least there
            drname = '%c:\\' % chr(ord('A') + d)
            t = win32file.GetDriveType(drname)
            if t == win32file.DRIVE_REMOVABLE:
                drive_list.append(drname)
    return drive_list
