Low-cost USB 2.0 protocol analyser combines high speed with advanced
The new Ellisys USB Explorer 200, now available from Computer Solutions,
is a low-cost, high-speed, non-intrusive full USB 2.0 protocol analyser. It
allows users to display the bus states, the contents of packets and whole
transactions sent, decode the descriptors, detect errors and
incompatibilities in devices or drivers, and measure their performance.
The Explorer 200 is a fully USB 2 compliant analyser which is able to
operate at all the USB speeds - 1.5 Mbit/s, 12 Mbit/s and the 'high-speed'
480 Mbit/s. It will automatically detect the speed being used and adjust to
An important new feature of the analyser is a set of USB protocol decoders,
including mass storage (as used by Flash disks, USB drives etc.), still
image (used by digital cameras), video (used by Webcams), audio (used by
speakers and audio systems), human interface devices (used by mice,
keyboards, joysticks etc.), printers, Bluetooth devices and communication
systems (used by modems, Ethernet adaptors etc.).
The unit will also decode the 'On the Go' protocol, as used by USB
peripherals communicating in the absence of a PC, such as a camera that
prints directly to a printer. Other advanced features include field
validation, context extraction and user-friendly data decoding.
In operation, the analyser is connected between a USB host and any USB
peripheral. It then provides a detailed view of the traffic on the line. As
the data packets are captured, the real-time statistics display provides a
check on the transactions status even before the individual packets are
The USB transactions and transfers are displayed in a chronological list
together with the peripheral's address and the endpoint number. A second
window gives details of the selected item. To make it easier to identify
specific packets, the software provides filtering and packet colour coding
The Explorer 200 is very simple to use, making it the ideal companion for
anyone developing USB devices, hosts, embedded software or drivers. It can
be used by those developing devices that use the protocols to help with the
development, or by those using the protocols within applications by hiding
the detail and just showing the data areas.
Its low price makes the unit affordable on a 'one unit per engineer'
basis for USB development teams.
