首先，您需要使用规则来检测USB存储设备

/etc/udev/rules.d/10-usbmount.rules：

KERNEL=="sd*[!0-9]|sr*", ENV{ID_SERIAL}!="?*", SUBSYSTEMS=="usb", RUN+="/usr/bin/usbdevinserted"

这将运行我们的自定义可执行shell脚本/usr/bin/usbdevinserted：

#!/bin/bash

set 2>&1 >> /tmp/usbdevinfo

此示例脚本转储您需要知道找到哪个设备的环境变量，例如：

DEVLINKS='/dev/disk/by-id/usb-Generic_USB_Flash_Disk-0:0 /dev/disk/by-path/pci-0000:00:13.2-usb-0:2:1.0-scsi-0:0:0:0'
