## What it is
A low-cost open-source hardware and software USB protocol sniffer supporting Low-, Full-, and High-Speed USB, built on a Cypress FX2LP MCU, Lattice FPGA, and USB PHY. It captures traffic in PcapNG format and integrates with Wireshark via a plugin, or runs standalone from the command line.

## Use cases
- capture and analyze USB traffic in Wireshark
- debug USB device communication at the packet level
- sniff low-speed, full-speed, and high-speed USB protocols
- save USB captures as pcapng files
- build a cheap DIY USB protocol analyzer
- reverse-engineer USB device protocols

## When to choose
- you need a low-cost hardware USB sniffer with full LS/FS/HS support
- you want USB captures directly in Wireshark
- you need open-source hardware with provided schematics, gerbers, and firmware

## When to avoid
- you only need software-only USB monitoring on Linux (usbmon may suffice)
- you need USB 3.x SuperSpeed capture
- you don't want to assemble hardware or solder a custom board
