## What it is
USBPcap is an open-source USB packet capture tool for Windows, consisting of a filter driver and a command-line capture application (USBPcapCMD). Captured traffic is written in pcap format and can be analyzed in Wireshark, which has native USBPcap support.

## Use cases
- capture USB traffic on Windows
- sniff USB packets for protocol reverse engineering
- debug USB device communication
- analyze USB traffic in Wireshark
- record USB packets to a pcap file

## When to choose
- you need to inspect USB traffic on Windows 7/8/10
- you want Wireshark-compatible USB captures
- you are reverse-engineering a USB device protocol

## When to avoid
- you need USB capture on Linux or macOS (use usbmon or similar)
- you require a signed production driver without test signing
- you need a GUI-only capture tool
