VUSB-ANALYZER(1)					       Virtual USB Analyzer						  VUSB-ANALYZER(1)

NAME

       vusb-analyzer - tool for visualizing logs of USB packets

SYNOPSIS

       vusb-analyzer [OPTIONS] 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.

NAME

       oss_usb - USB Audio/MIDI/Mixer driver

DESCRIPTION

       The Open Sound System driver for USB Audio and MIDI devices.

   AUDIO
       The Audio driver supports:

       o  8-96Khz Playback/Recording

       o  8 or 16 or 32 bits

       o  2, 4, 6 or 8 channel audio.

       o  SPDIF digital output and Input

       o  AC3 passthrough

       o  Volume control and device input mixer

   MIDI
       The  oss_usb driver supports all MIDI devices that are compatible with the official USB MIDI specification. In addition the driver supports
       few devices that use their own private protocol (including some Yamaha and Midiman models).

   USB MIXER
       The USB Audio mixer is a new type of mixer that doesn't have the normal volume controls found on AC97 or Legacy SB devices.  The USB  audio
       mixer provides control for selecting the Alternate device setting - this usually allows the device to be switched into a Professional audio
       mode (eg 24bit or 96Khz mode)

   ALTERNATIVE SETTINGS
       Some USB audio devices use a feature called as alternative settings for bandwidth management. Typically such  devices  have  multiple  high
       speed  inputs  and outputs that may require more bandwidth than provided by the USB bus. The alternative settings feature is used to select
       between multiple low speed devices or just few high speed devices.

       When the device has multiple alternative settings an "altsetting" selector will be visible in the control panel for the	device	(use  oss-
       mix(1) or ossxmix(1) to change it). Alternative setting OFF means that all audio devices are disabled. The other settings provide different
       combinations of high/medium speed devices. You can use the ossinfo(1) command (ossinfo -a -v3) to find out the  devices	supported  by  the
       currently selected alternative settings and the capabilities of them.

KNOWN BUGS

       Under  Linux  it  is necessary to run the ossdetect -d and ossdevlinks commands after an USB device has been hot-plugged. Alternatively you
       can execute soundoff and soundon to reload OSS.

OPTIONS

       None

FILES

       /etc/oss4/conf/oss_usb.conf Device configuration file
