With USBTrace you can monitor your devices with ease. Just select the device to
be monitored and click 'capture'.
Ease of viewing captured data
USBTrace decodes each and every captured USB request, and displays it in an
easily readable form. Data buffer, if any, associated with the request is also
USB requests at all levels
With USBTrace you can monitor USB requests at USB Host Controllers, USB
Hubs and USB devices.
does not use any filter drivers
Unlike other software analyzers, USBTrace does not use any filter driver to
capture the USB requests. So USBTrace will not disturb the PnP system due to
all USB requests during device enumeration
USBTrace is capable of capturing all USB requests exchanged between the host
controller/hub and the device during device enumeration.
valuable information for WDM device driver developers
The IRP, URB and IO_STACK_LOCATION structures associated with each
captured request is decoded and displayed by USBTrace. Also, in addition to
capturing URBs, USBTrace captures Internal USB IOCTLs, User mode USB
IOCTLs, PnP and Power IRPs.
USBTrace also allows WDM driver developers to capture USB requests
made/received by any device object in the USB device stack.
can be setup to automatically capture hot plugged devices
With this option enabled, USBTrace will capture USB requests from all newly
plugged devices. This option can be used to monitor USB requests during device
and Filter captured requests
Advanced search feature allows you to search the capture log for request types
and/or buffer contents of requests.
The filtering feature allows you to exclude requests which you are not interested
in while capturing.
The captured information can be saved for storage and later viewing.
log as HTML, XML or Text
The new Export Utility allows you to export the logged USB transactions as an
HTML, XML or text file, in addition to the native USBTrace binary file format.
capturing for improved performance
Background capturing facilitates high performance capturing. The GUI is not
updated while capturing. The logged transactions are displayed only when
capture operation is stopped.
For a normal capture session, USBTrace will stop capture operation when the
internal log data buffer is full. With continuous capturing, this will not happen.
When the buffer is full, instead of stopping capture, USBTrace will wrap around
the buffer and start writing data again from the beginning.
Continuous capturing simulates an infinite buffer.
Trigger facility allows you to define a condition and capture operation will stop
automatically when that condition is satisfied.
USBTrace is compatible with the latest version of the Windows operating system.
Export USB device, hub or host controller information (general device details,
connection information, device descriptors) to an html or txt file.
USBTrace provides detailed decoded information regarding class specific
requests. The device classes currently supported are HID, Hub, Mass Storage,
Communication Device (CDC), Bluetooth, Still Image Capture, Audio, Video,
Smart Card Reader, Printing devices, PHDC, Test and Measurement (TMC),
Wireless USB Host Wire Adapter (HWA) & Vendor Specific device class.
Send your reports directly from the application
USBTrace customers can send error reports/feature requests directly from the
The Performance Statistics feature allows you to extract and display a lot of
valuable information (performance counters) from the captured data. The
performance statistics window displays the following information for Control,
Bulk, Interrupt & Isochronous transfers :
Total data read from device, Total data written to device, Passed & Failed
request count, Average and Maximum read/write data transfer rates.
In addition to displaying the performance counters, the performance statistics
window also displays a graphical representation of the read and write data
device traffic directly to file
Using this feature you can route the data captured from devices directly to a file
on your hard disk (or any other storage device). The user interface will not be
updated during capture operation. This results in high performance capture
sessions which can capture large amount of data. This feature also helps to
debug unstable or faulty systems by ensuring that the captured data is not lost
even if the system crashes/restarts during capturing.
Add Comments and Bookmarks
The Comment and Bookmark features allows you to add notes and highlight
captured requests. This helps you to document the captured data. When the
capture log file is shared with a colleague or when you open the log file later, the
comments which you have added helps to understand the captured data easily.
Bookmarked requests are highlighted and can be easily identified.
Set any captured request as 'time 0' request
Any request can be set as the timing reference request using this feature. The
timestamp of the selected request will be set to zero and those of others will be
marked relative to this reference request. This feature is helpful to find the timing
of various USB transactions in reference to a selected transaction.
User defined template to decode data
You can define structure formats using which the captured data will be decoded.
Structure definitions are specified via an XML file.
Supports SuperSpeed USB (USB 3.0)
Supports USB 3.0 host controllers, hubs and devices and decodes all newly
introduced standard descriptors and requests.
