USBDriveLog is a lightweight, portable freeware tool created by NirSoft that extracts and displays a history of all USB drives plugged into a Windows computer. It acts as a forensic and diagnostic log viewer, reading hidden Windows event logs to show you exactly what external storage devices have been connected to a system, even long after they have been unplugged.
Whether it is the “best” free USB logger depends on what you need. It is arguably the best tool for historical analysis of USB storage drives, but it is not a real-time protocol data packet analyzer or a device blocker. Key Features
Detailed Device Forensic Data: It pulls deep information including the device model, manufacturer, serial number, device ID, firmware revision, and storage capacity.
Exact Timestamps: The tool displays the exact Plug Time and Unplug Time for every single connection event.
Remote & External Auditing: You can pull USB logs from your local computer, a remote computer across a network, or an external hard drive (shadow copies/offline system registries).
No Installation Required: Like most NirSoft utilities, it is fully portable. It runs out of a tiny standalone .exe file without modifying your registry or leaving a footprint.
Flexible Data Export: You can easily search using Ctrl+F and export the logged results into Text, CSV, XML, JSON, or HTML files. How It Works Behind the Scenes
Unlike older real-time monitoring tools that need to actively run in the background to catch an event, USBDriveLog operates retrospectively. It automatically parses data from two specific Windows event log channels that are turned on by default in modern operating systems: Microsoft-Windows-Partition/Diagnostic Microsoft-Windows-Storsvc/Diagnostic Pros & Cons 100% Free: No ads, subscriptions, or telemetry.
Strict OS Limitations: Only works on Windows 10 and Windows 11; older versions lack the required log channels.
Instant Historical Data: Shows past events even if the tool wasn’t running when the USB was plugged in.
Storage Only: It only tracks USB mass storage (flash drives, external HDDs), not keyboards, mice, or phones.
Extremely Lightweight: Takes up minimal disk space and utilizes near-zero CPU resources.
Dependent on Windows Logs: If a user clears the Windows Event Logs or disables diagnostics, USBDriveLog will show nothing. Is It the Best Free USB Logger? (The Alternatives)
While USBDriveLog is unmatched for checking historical USB storage events on Windows ⁄11, other freeware tools might serve your needs better depending on the context: USB Drive Log For Windows 10 and Windows 11 – NirSoft
