USBTrace : Features

With USBTrace you can monitor your devices with ease. Just select the device to be monitored and click 'capture'.

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 displayed.

With USBTrace you can monitor USB requests at USB Host Controllers, USB Hubs or USB devices.

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 its presence.

USBTrace is capable of capturing all USB requests exchanged between the host controller/hub and the device during device enumeration. See USB Enumeration Explained to know how USBTrace is different from other USB monitor software.

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.

See Complete list of USB requests captured, decoded and displayed by USBTrace.

USBTrace also allows WDM driver developers to capture USB requests made/received by any device object in the USB device stack.

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 enumeration.

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. You can also apply filters based on endpoint addresses.

Comment and Bookmark features help you to document the captured data by adding notes and highlights.

View USB Device, Hub, Configuration, Interface, Endpoint descriptors & Windows specific USB enumeration information. Device information can be exported as an HTML or text file.

Supports device class decoding
USBTrace can decode class specific usb descriptors/requests and display detailed information regarding them. Read more about class decoding

You can shutdown, hibernate or standby your system while running USBTrace.

The captured information can be saved for storage and later viewing.

The new Export Utility allows you to export the logged USB transactions as an HTML, XML, text or CSV file, in addition to the native USBTrace binary file format.

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.

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.

Trigger facility allows you to define a condition and capture operation will stop automatically when that condition is satisfied.

Performance Statistics feature allows you to extract a lot of valuable performance related information from the captured data. The values of various performance counters and Read/Write data transfer rate graph are displayed. Performance statistics can be exported as an HTML or text file.

USBTrace users can send error reports/support queries directly from the application.
