    • USB device stack layout: Device objects for each driver that is involved in handling I/O activity.

    • USB descriptors: Device Descriptor, Configuration Descriptor, Interface Descriptor, Endpoint Descriptor, etc.

    • Information related to Plug and Play: Hardware IDs, Instance ID, Software Key, etc.

  • Capture, decode and display important information going through USB device stack:

    • USB-related requests such as URBs and structures used by USB device drivers.

    • I/O Request Packets (IRPs) used by PnP subsystem.

    • Kernel-mode and user-mode device I/O control requests (IOCTLs) used by USB client drivers and user-mode applications.

    • Incoming and outgoing data traffic of the USB devices.

  • Trace USB requests that the user-mode applications and USB device drivers use to communicate with the USB driver stack.

  • Analyze USB protocol and USB devices I/O activity with ease.

  • Filter to exclude non-essential information from the view.

  • Search the captured data for the particular request types.

  • Save captured data in binary file for later analysis.
