COM Device Notifier

PowerShell Script for notifying when a COM device is (un)plugged

Requirements

This script requires the BurntToast Module (PowerShell Gallery)

The script has been tested on PowerShell 7.1, but should work on 5.1+

Install

The script must run in the background of the user session. The best option is to add a scheduled task.

Scheduled Task

• Add a scheduled Task, name it like you want (ComDeviceNotifier)
• Run only when user is connected
• Trigger : At User Login
  • Since the script is only accessible to my user, I make sure the task only runs when my user is connected
• Action : Start a program
  • Executable : pwsh.exe
  • Arguments : -WindowStyle Hidden -NoProfile -NonInteractive -NoLogo -NoExit -File "C:\Users\vezal\gitrepos\ComDeviceEventNotif\Start-ComDeviceNotifier.ps1"
• Conditions : I allow the task to be run on battery power
  • Because generally, when I need to know what COM port I just plugged, I'm on the move.
• Parameters : If the task is already running, stop the existing instance.

Stopping notes

To stop the process, stop the scheduled task or the running thread in the task manager.
