A careful USBPcap install is more than clicking through a setup wizard. The software adds a USB filter driver, so the machine should have a recovery option and the package should come from the official project source. The process below focuses on preparation and validation rather than assuming every Windows version behaves the same way.
Before you install USBPcap
- Save current work and close applications that use USB hardware.
- Create a restore point or another recovery method appropriate for the machine.
- Confirm the operating system is not booting from a USB drive.
- Remove nonessential USB devices.
- Check the latest official release notes for supported Windows versions.
Source archive versus installer
The download supplied on this site is a GitHub source archive from the project's master branch. Source code can be reviewed or built by experienced users, but it should not be described as the latest signed installer. End users should compare it with the current release assets at the official source.
Installation sequence
- Verify the package source and, where available, its signature or published checksum.
- Run the trusted installer using an administrator account.
- Read every driver prompt and confirm that it names USBPcap.
- Allow the installation to complete without connecting or removing devices.
- Restart Windows if the installer or release notes require it.
Manual driver builds are for advanced users
The project repository includes developer build instructions and driver source. Building or manually installing a driver requires the correct Windows Driver Kit, signing configuration, and knowledge of test-signing modes. Most users should not enable system-wide test signing simply to experiment.
Confirm the installation
- Open Wireshark and look for USBPcap capture interfaces.
- Check Device Manager for new warnings.
- Verify that keyboard, mouse, storage, audio, and other USB devices still operate normally.
- Run a short capture from a test device.
- Stop and save the result before starting a longer diagnostic session.
What not to do
Do not install on a production computer without a rollback plan. Do not delete arbitrary USB registry keys if something goes wrong. Do not combine old drivers, third-party repackaged installers, and current Wireshark builds without documenting exactly what was installed.
After installation
Keep a record of the USBPcap release, installation date, Windows build, and removal method. That small record is useful when a future Windows update changes driver behavior or when another technician needs to reproduce the environment.
