Chapter 1: Starting out
Introduction
The Ellisys USB Explorer 260 is a sophisticated protocol test system for USB traffic
monitoring, driver and software stack debugging, protocol compliance verification and
performance analysis. The EX260 can reduce your R&D development time by finding
issues early and debugging more efficiently, and can improve quality and reliability by
verifying compliance to the specifications.
The Ellisys USB Explorer 260 is available in three configurations:
The Ellisys USB Explorer 260 Analyzer includes Ellisys' analysis features with
real-time monitoring, hard-disk data streaming, class decoding, traffic statistics,
and triggering and filtering.
The Ellisys USB Explorer 260 Generator supplements protocol analysis by
emulating USB devices and hosts, and by testing corner cases and recovery
mechanisms. Reproducible traffic, timing and error scenarios can be created
with a scripting environment. Captured traffic can be replayed to test a
particular situation. The Generator supports Inline Error Injection feature to
insert programmed errors between a host and device to determine the impact of
transmission errors under rare conditions.
The Ellisys USB Explorer 260 Duo is a flexible bundle of two full-featured
units that can be used as one analyzer and one generator, two analyzers or two
generators depending on your testing requirements. More convenient than
having both functions on the same unit, this allows you to better share your test
equipment among your R&D team.

Common terms
The following terms are used throughout this manual:
Analysis software The analysis software enables users to record data sent
by the analyzer and subsequently displays them in a
simple, easy-to-follow format.
Generator software The generator software enables users to write, run and
debug generator scripts.
Device Under Test A USB device that is going to be analyzed with the
analyzer is called a device under test in this document.
Host Under Test The device under test will be plugged into the Host Under
Test through analyzer's Link Under Test connectors. The
Host Under Test can be any host including a PC, an
embedded computer, a PDA or even a custom piece of
equipment acting like a USB host.

Chapter 2: Connecting the unit as protocol analyzer
Introduction
The Ellisys USB Explorer 260 Analyzer is a non-intrusive USB protocol analyzer that can
connect on any link between any host controller and device.
InterChip USB is supported with an optional analysis probe that connects directly
on the USB link between the embedded host and device on a PCB board. Please
The EX260 Analyzer sends data using a High-speed USB 2.0 connection. Although the
unit can download analyzed data on a Full-speed USB 1.1 connection, it is strongly
recommended that you connect it using a High-speed USB 2.0 port to obtain optimal
performance. If you experience any trouble with your analyzer, please ensure it is
connected on a High-speed USB 2.0 enabled host controller before contacting our
technical support.
The Power LED of the front panel is illuminated in green when the unit is
connected on a High-speed USB 2.0 link, and in red when connected on a Full-
speed USB 1.1 link.
Connecting the Analyzer to a computer
Configuration with two computers: recommended configuration
The use of two computers is the recommended configuration (see Figure 1). The Host
Under Test is ascribed to the Device Under Test, and the analysis computer handles
downloads and analyses data coming from the analyzer.
Figure 1 - Configuration with two separate computers

Version 1.0.0 November 22, 2007
Configuration with only one computer
It is possible to use just one computer for both testing and analysis (see Figure 2), but
this may affect the performances of the real-time data monitor and download. You
must, however, ensure that two or more host controllers are available on the
computer. If there is only one host controller on your computer, a CardBus or PCI
extension card can be purchased to add a second host controller to an existing
computer. Please refer to the chapter on Troubleshooting to determine if your computer
has two host controllers. The following diagram shows how to use the analyzer with
only one computer.

Connecting a device under test for analysis
Connecting only one Device Under Test
The most straightforward configuration involves only one device to be analyzed.
Figure 3 shows how to properly connect the device under test.

To prevent problems which could arise from your cables' length, please follow the
following instructions:
-The blue cable must be no longer than 5 meters.
-The total length of the red and purple cables must not exceed 3 meters. A
greater length could result in an abnormally high error rate on the bus being
analyzed.
