Human Interface Device (HID) class support added. Now we parse and display HID reports in an easy to view form, decode and display HID class-specific descriptors (HID Descriptor and HID Report Descriptor), decode all HID class-specific requests (Get Report, Set Idle, Get Protocol etc.). Read more about HID class decoder.

Compound and composite devices with HID class interface(s) are supported.

Syncing Capture List with Device Tree + Auto Sync feature.

2440 vendors recognized.

When displaying the time, we previously only showed the absolute system time the I/O request was captured. Now you can configure USBlyzer to display the time in the following formats:

• Absolute system time (11:45:14.278)

• Time elapsed since capture started (00:00:15.953)

• Seconds elapsed since capture started (2.396)

To configure the time display settings, new section was added in the Preferences Dialog under Options->Preferences...->Time.

Hub Class support added. Now we decode all Hub class-specific requests (Get Hub Status, Clear Port Feature, Get Hub Descriptor, Reset TT etc.). Read more about Hub class decoder.

Request Summary analysis was significantly improved. When displaying the summary for Control Transfers, we previously only showed the Setup Packet in raw format. Now the summary analysis is much more specific and relevant for all USB Standard and USB Hub Requests.

Previously we only captured state-transition Plug and Play IRPs (start, stop, remove). Now USBlyzer captures and decodes all Plug and Play IRPs. The following was added:

• IRP_MN_QUERY_DEVICE_RELATIONS

• IRP_MN_QUERY_INTERFACE

• IRP_MN_QUERY_CAPABILITIES

• IRP_MN_QUERY_RESOURCES

• IRP_MN_QUERY_RESOURCE_REQUIREMENTS

• IRP_MN_QUERY_DEVICE_TEXT

• IRP_MN_FILTER_RESOURCE_REQUIREMENTS

• IRP_MN_READ_CONFIG

• IRP_MN_WRITE_CONFIG

• IRP_MN_EJECT

• IRP_MN_SET_LOCK

• IRP_MN_QUERY_ID

• IRP_MN_QUERY_PNP_DEVICE_STATE

• IRP_MN_QUERY_BUS_INFORMATION

• IRP_MN_DEVICE_USAGE_NOTIFICATION

Added capturing and decoding support for the following Windows® Vista™ URBs:

• URB_FUNCTION_CONTROL_TRANSFER_EX (URB_CONTROL_TRANSFER_EX structure)

• URB_FUNCTION_SET_PIPE_IO_POLICY (URB_PIPE_IO_POLICY structure)

• URB_FUNCTION_GET_PIPE_IO_POLICY (URB_PIPE_IO_POLICY structure)

Added capturing and decoding support for the following Windows® Vista™ IOCTLs:

• IOCTL_USB_GET_HUB_CAPABILITIES_EX (USB_HUB_CAPABILITIES_EX structure)

When displaying the completed IRP status, we previously only showed the completion status of the IRP itself in the IRP Status column of the Capture List. Now for all completed URBs you can also see the USBD_STATUS. This might be very useful. For example, for failed URB_FUNCTION_SYNC_RESET_PIPE_AND_CLEAR_STALL you might see "Unsuccessful (Device not Responding)" instead of just "Unsuccessful". So in this particular case you know that URB failed with USBD_STATUS_DEV_NOT_RESPONDING, by just looking at Capture List.

Export Capture List content to XML report.

New Capture List column "Request Details" has been added. This feature is extremely useful in analyzing the captured data and greatly speeds up the analysis process. Now you can see, at a glance, by just looking at Capture List the Number of Bytes transferred for bulk and isochronous transfers, the Port Number for IOCTL_USB_GET_NODE_CONNECTION_XXX I/O control requests, Request Type and Recipient for control transfers and more. The table below is the complete list of the data that will be displayed in the Request Details column.

New Data Analysis Panel has been added. When displaying the data buffer contents, we previously only showed the raw hexadecimal dump in the Raw Data Panel. Now you can also see the complete analysis for many types of requests in Data Analysis Panel. USBlyzer is able to verify the general compliance of USB Request Packets with the USB Specification. Any incompatibilities are marked with red color. The table below is the complete list of the data that will be decoded and displayed in details on the Data Analysis panel.

The USB Properties panel has been completely re-designed and now the USB device descriptors and related information are presented in much greater details.

USBlyzer is now able to verify the general compliance of all standard USB descriptors with the USB Specification. Any incompatibilities are marked with red color in the USB Properties panel.

The content of the USB Properties panel can now be exported to the HTML report.

Capture Settings, Filter Settings and Find Settings dialogs are now resizable.

The Capture List is now colorized. You have three options: colorize entire row, type column only or not colorize at all.

The Device Manager's device properties dialog box can be invoked by right-clicking the specific device in the Device Tree and then clicking Properties. This allow you view information about a device driver, bandwidth allocations for USB host controllers, power allocations for USB hubs and more.

The device tree now displays the drive letter that is assigned to each USB mass-storage device such as USB Flash Drive, USB CD-ROM Device, USB Card Reader etc.
