问题
I am trying to get a script to run whenever ANY USB flash drive (not just a specific one) is plugged in to the system and I have been pulling my hair out for about 2 weeks now on and off trying to figure it out. Can anybody help me? (running Ubuntu if that helps).
I need to be able to pass the drive serial number and the devpath (/dev/sd**) at bear minimum.

First you need your rule to detect usb storage devices
/etc/udev/rules.d/10-usbmount.rules:
KERNEL=="sd*[!0-9]|sr*", ENV{ID_SERIAL}!="?*", SUBSYSTEMS=="usb", RUN+="/usr/bin/usbdevinserted"
This runs our custom executable shell script /usr/bin/usbdevinserted:
#!/bin/bash
set 2>&1 >> /tmp/usbdevinfo
This sample script dumps the environment variables which you will need to know which device was found, eg:
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'
