Compact, cross-platform hardware USB Protocol Analyzer.

Capture, debug and analyse USB connections easily and economically.


The BugBlat EzSniffer is a simple, economic USB Sniffer / Protocol Analyser solution.

Compact, powerful and cross-platform, it is bundled with a mature cross-platform software suite for capturing and displaying USB traffic.

The ezSniffer can capture up to 256MB of compressed data but requires a host computer to work. If you require untethered operation, we recommend the miniSniffer.

The ezSniffer is a special purpose logic analyzer. An on-board FPGA samples the USB signals, compresses the samples, and sends the compressed data to an analysis PC via the FX2LP's buffered high speed USB link. Software on the analysis computer decompresses the samples and converts them into a visual flow:

    Functionality in a glance

    Below is a non-exhaustive list of the EzSniffer's advantages:

    Budget USB Analysis

    Full-speed and high-speed USB Analysis

    Fully Cross-Platform

    Bundled software works on Windows, Mac and Linux

    Pocket-sized Inspection

    Highly capable yet half the size of a credit card.

    Detailed functionality

    • Disconnect and reconnect USB devices. This makes it straightforward to capture startup packets, including descriptors.

    • Compresses capture data. It can capture up to 256MBytes of compressed data.

    • Sniff USB Full-Speed (FS) device traffic at 12Mbit/s.

    • Sniff USB High-Speed (HS) device traffic. 480Mbit/s High-Speed devices power up as FS devices and then attempt to move up to HS. The ezSniffer prevents HS devices moving from FS to HS, so the ezSniffer can sniff these devices as well.
