WTF just disconnected? Real-time USB device monitor for Windows with a neon-themed GUI, event logging, and CLI mode.
v0.8.0 — Tauri v2 + Svelte 5 rewriteComplete Tauri v2 + Svelte 5 rewrite. Glassmorphism UI, 5 themes, full emoji support.
Features
Everything you need to track what's happening on your USB bus.
Live Monitoring
Background thread polls WMI every 500ms. Instant detection when devices connect or disconnect.
Event Cards
Color-coded cards with left accent bars. Green for connect, red for disconnect. Timestamp, device name, VID:PID, class, manufacturer.
5 Premium Themes
Neon, Catppuccin Mocha, Dracula, Nord, and Solarized Dark. Smooth 300ms transition between them. Glassmorphism panels with backdrop blur.
Known Devices Database
Remembers every device ever connected. Search, sort by 5 modes, set nicknames, view first/last seen timestamps and connection count.
Storage Detail Panel
Click any storage device to see animated capacity bars (green→yellow→red), volume info, model, serial, firmware, interface type.
File Logging
Every connect/disconnect event is logged to device-history.log with millisecond timestamps. Survives restarts.
CLI Mode
Run with --cli for colored terminal output. Same monitoring, no GUI. Pipe it, script it, watch it in a terminal.
System Tray
Closing the window hides to the system tray instead of quitting. Right-click to show, hide, or exit. Double-click to restore. Always watching, never in the way.
Device Nicknames
Rename any device to something you'll actually recognize. "USB Composite Device" becomes "Quest Link Cable" or "Wacom Tablet". Persisted across sessions.
Known Devices
Remembers every device it's ever seen with first-seen and last-seen timestamps. Build a history of your USB ecosystem over time.
Search & Sort
Filter devices and events by name, ID, or class. Sort by any column. Find what you're looking for in a list of 50+ USB devices.
Update Checker
Silently checks GitHub for new releases on startup. If a newer version exists, a clickable banner appears in the header.
How It Works
Simple WMI-based polling with diff detection.
Query WMI
Queries Win32_PnPEntity for all USB devices via the wmi crate. Gets name, device ID, description, manufacturer, and PnP class.
Snapshot & Diff
Takes a device snapshot every 500ms on a background thread. Diffs against the previous snapshot to find new and removed devices.
Log & Display
New events are pushed to the shared state, logged to file, and rendered as neon-styled cards in the GUI.
Tech Stack
Rust for speed and safety. Single binary, no runtime dependencies.
