SYNOPSIS¶
vusb-analyzer [

LOGFILE [
LOGFILE...]
DESCRIPTION¶
The Virtual USB Analyzer is tool for visualizing logs of USB packets, from
hardware or software USB sniffer tools. It's the world's first tool to provide
a graphical visualization along with raw hex dumps and high-level protocol
analysis.
The Virtual USB Analyzer is not itself a USB sniffer tool. It is just a user
interface for visualizing logs. It currently supports two log formats, but
it's designed to be easily extensible. With a couple hundred lines of Python
code, you can add support for your favorite log format.
The Virtual USB Analyzer was developed at VMware as an efficient way to debug
their own USB virtualization stack. They wanted a tool that made it easy to
see problems at a glance, and they wanted a way to solve both correctness and
performance bugs. As a result, they ended up with what they think is a fairly
unique tool. They're excited to have the opportunity to release this tool as
open source software.
Supported Log Formats
* Logged USB traffic from debug builds of VMware Fusion, Workstation, or Player.
See the tutorial for information on capturing such a log.
* XML logs from the Ellisys USB Explorer 200, a hardware USB 2.0 analyzer.
Features
* Unique graphical timeline view.
* Side-by-side diff mode: visually compare two log files.
* Pluggable log format modules: VMware, Ellisys.
* Pluggable protocol decoders: USB Chapter 9, Bluetooth, Storage, Cypress FX2.
* Packet metrics and filtering tools.
* Whole-bus analysis: analyze multiple devices concurrently.
* Written in Python, with a GTK+ user interface.
* Automatic "tail -f" mode: follow log files as they grow.
* Loads large log files in the background. You can start browsing before the
whole file is loaded into memory.
* Automatic decompression of gzipped log files.
OPTIONS¶
- -t
- Tail mode, start from the end of a growing log file.
