SerialPlugNotify
A lightweight Windows utility for monitoring USB serial (COM) port plug and unplug events.
What does it do?
When you plug in or unplug a USB serial device (e.g. Arduino, CH340, FTDI), it will:
- Show a Windows toast notification with the COM port number and device name
- Log each event in a table — time, device, port, and action
- Update the system tray tooltip with the currently connected COM ports
Features
- Real-time detection using Windows API events (not polling)
- Event log table with sortable columns and right-click copy
- Runs in the system tray, no taskbar clutter
- Optional auto-start at Windows login
- CSV export and file logging
