Sometimes you need to monitor USB transactions performed by user USB application communicating with device driver (via Windows API functions calls) and accessing USB hardware device using standard or vendor-specific USB interfaces. On the USB protocol layer level such debugging tools as USB logic analyzers and oscilloscopes makes almost no sense due to it's low level view. The most applicable tool in this case will be USB Protocol Analyzer where communication data is parsed and decoded from binary raw format into a human-readable form, which allows you to review the exchanged data and perform effective forensic analysis of packets.
Our USB protocol analyzer works by installing a filter driver on top of USB host controller driver. The filter driver intercepts all communication between a USB driver and host controller driver and passes intercepted data to the running monitoring session. USB Monitor uses a set of predefined and user-created protocol definition files to parse monitored data, filter them according to specified criteria and process using various data processing modules.
It provides a rich set of USB class-specific visualizers, built-in Statistics module as well as logging module. The latter one can be used to create a detailed log of a monitoring session, which allows postponing session analysis. In addition, a custom data visualizer may be created which will present the essential data to the user in most convenient way. Data in each data visualizer can easily be navigated, searched, copied and exported in various formats.

Packet View: displaying monitored packets in a table
The Packet View visualizer provides the combination of brief packet information for each monitored packet and in-depth analysis for an individually selected packet. It is structurally divided into two panes.
The upper pane displays brief information for each monitored packet in a table. The lower pane lists all other supported and installed visualizers which are used to display the individual packet information. Once you select the packet in the upper pane, all its internal fields are decoded and displayed in the visualizers in the lower pane. For example, you may select a HID protocol packet to see it decoded in URB View and HID View visualizers.
URB View: displaying monitored USB Request Blocks
The URB View visualizer displays each monitored USB Request Block (URB). It decodes the packet's internal fields, and works in two modes - Basic and Complete. In Basic mode only the main packet fields are decoded and displayed, while some other are available as popup hints. In Complete mode the entire packet is decoded and all accompanying data is provided in Hex/ASCII view.
The contents of the visualizer can be copied into the Clipboard or exported into the file in various formats. Use the mouse to select the portion to copy/export or leave the selection empty to copy the entire visualizer contents.
Structure View: parsing & displaying USB packet data
Structure View data visualizer is a two-part window. First part displays each monitored packet parsed according to specified set of protocols. Second part displays raw packet contents. Cursor navigation may be synchronized between two parts. Each packet is matched against one or more of loaded protocol definition files and all protocol fields are shown in the top part of the visualizer. For each field, its name, value, starting address and size are displayed. If field consists of other fields, you may expand it.
Visualizer supports configuring protocol-based filtering (aka Display Filter) and allows changing of the root protocol.
Raw Data View: displaying raw packet data
The visualizer has two windows, one of which displays data sent to the USB device, and another one displays data received from the USB device.
All subsequent packets are concatenated into a single data stream, which is displayed as sequence of hexadecimal, decimal, octal, binary data and text. Alternatively, the stream may be displayed as a sequence of floating-point numbers with single or double precision.
The data visualizer is extremely flexible and allows you to customize both its layout and appearance.
HID View: parsing of Human Interface Device (HID) packets
The HID View visualizer parses and displays the contents of the HID report descriptors and HID-specific requests. This visualizer works in two modes: HID View and Report View.
In HID View mode the visualizer displays parsed HID Report descriptor and brief description for each monitored HID packet. In Report View, the most detailed information for each monitored packet is displayed.
Still Image View: parsing of USB Still Image and MTP packets
The Still Image/MTP View visualizer parses and displays the commands and data exchanged between device and host over USB Still Image and MTP protocols. These protocols are used by digital still photography devices.
The complete PIMA 15740 command set is supported, all PIMA 15740 operations, responses and events are decoded and displayed.
Mass Storage View: parsing of USB Mass Storage packets
Works with USB Mass Storage Bulk-Only device class and subclass. Specific commands from USB Mass Storage CBI are also supported. There are two modes of operation: Mass Storage Level and Command Level. In first mode it parses Mass Storage-specific structures, and in the second mode it parses commands exchanged between the host and device.
The following command sets are supported: SCSI Primary Command Set 2 (SPC2), SCSI Multimedia Command Set 2 (MMC2), SCSI Reduced Block Command Set (RBC)
Audio View: parsing of USB Audio packets
USB Audio visualizer parses packets and descriptors for USB Audio compliant device. The following subclasses are supported: Audio Control (AC) & Audio Streaming (AS). The first one is used to control and change the state of device. The second one is generally used for data transmitting.
The following control pipe requests are parsed for the audio class device: SET_CUR (0x01), GET_CUR (0x81), SET_MIN (0x02), GET_MIN (0x82), SET_MAX (0x03), GET_MAX (0x83), SET_RES (0x04), GET_RES (0x84), SET_MEM (0x05), GET_MEM (0x85), GET_STAT (0xFF)
Video View: parsing of USB Video packets
USB Video visualizer parses packets and descriptors for USB Video compliant device. The following subclasses are supported - Video Control (VC) & Video Streaming (VS). The first one is used to control and change the state of device. The second one is generally used for data transmitting.
Communications View: parsing of USB Communications packets
This visualizer decodes USB Communications Class packets and descriptors. The Communication Device Class is a device level definition and is used by the host to properly identify a communication device that may present several different types of interfaces.
A filter is a single condition which follows the syntax of Protocol Definition expressions. Capture filter can be used to discard entire packets according to specified criteria. It can refer to any field in captured packet and use logical or arithmetic operators.
You can either select one of the predefined filters or create your own.
USB endpoints filtering feature
Device Monitoring Studio offers an endpoints filtering feature, which allows you to select endpoints to be filtered using context menu in URB View visualizer.
Combined with an ability to have as much URB View visualizers as you need, you may open one data visualizer for each endpoint.
Raw data exporter
This exporter parses intercepted USB data according to the loaded set of protocols, applies optional protocol-based filtering and Root Protocol and writes the resulting binary data into the output file. It produces the result identical to the lower part of the Structure View data visualizer, but does not display any UI, writing raw data directly to the file.
This exporter parses intercepted USB data according to the loaded set of protocols, applies optional protocol-based filtering and Root Protocol and writes the resulting text data into the file. It formats its textual output exactly like the upper part of the Structure View visualizer, but does not display any UI, writing formatted data directly to the file.
USB Monitor comes with a lot of pre-installed protocols. This feature also allows the customer to add the definition of the custom protocol to USB Monitor. After this, the application will start parsing and decoding all matching packets according to custom protocol definition.
Custom Visualizer allows the user to create his own visualizer in TypeScript. Custom visualizer receives each packet parsed according to selected protocol and adds one or more text strings to the output. It also defines several visual schemes which may later be customized by the user.
Root protocol, a feature of Structure View data visualizer, as well as several other components, allows the user to focus on a specific custom protocol frame inside another encapsulating protocol.
This feature supports joining monitored data from multiple USB devices into a single monitoring session. Device Monitoring Studio makes sure packets are correctly sorted and presented through a number of supported data visualizers. Data logging also supports multi-source sessions.
