Introduction to Capturing Bluetooth and USB Traffic with Wireshark

As connected devices become more prevalent, understanding and analyzing Bluetooth and USB traffic is essential to ensure seamless communication and troubleshoot any issues. In this guide, we will explore how to use Wireshark to capture Bluetooth and USB traffic and correctly install and use the NPCAP driver.

Installing the NPCAP Driver

To capture network traffic on a Windows operating system, Wireshark requires the NPCAP driver. NPCAP is an NDIS 6 packet capture driver, which is a part of the Nmap project. To install it, follow these steps:

  1. Download the latest version of NPCAP from the official GitHub repository or install the version that is coming with Wireshark.
  2. Run the installer as an administrator.
  3. During the installation process, select the appropriate options for your system, such as installing the driver only, installing the driver and its utilities, or installing the driver in WinPcap API-compatible mode.
  4. Restart your computer after the installation is complete.
