Universal Serial Bus (USB) protocol is very complex. So the USB support software present in Microsoft® Windows® operating system family is also complex and provides a layered architecture where the system-supplied and vendor-supplied user- and kernel-mode components can be involved in communications over USB. Transactions performed over the USB are basically initiated by the user applications which communicate with the operating system by calling Windows API functions which in turn interact with appropriate device drivers providing access to a USB device through standard and vendor-specific interfaces.

What do you do when you want to know what is going on inside the Windows USB subsystem? What USB drivers are used to connect various peripheral USB devices to a computer? What I/O requests, support routines, structures, and interfaces the core components of the Windows USB architecture use to communicate with the USB devices? What you need is a USB Protocol Analyzer.
Device Manager displays only non-Plug and Play devices, drivers, and printers when you click Show hidden devices on the View menu. Devices that you install that are not connected to the computer (such as a Universal Serial Bus USB device or 'ghosted' devices) are not displayed in Device Manager, even when you click Show hidden devices. Motorola Device Manager contains USB drivers and software to connect your Motorola phone or tablet to your computer using a USB cable. USB Manager, free download. USB management software for Windows: Manage connected USB devices from within the tray or context menus. Includes tests and PC download for 32-bit/64-bit systems completely free-of-charge. Having an issue with your display, audio, or touchpad? Whether you're working on an Alienware, Inspiron, Latitude, or other Dell product, driver updates keep your device running at top performance. Step 1: Identify your product above. Step 2: Run the detect drivers scan to see available updates. Step 3: Choose which driver updates to install.
Analyze and Realize USB Protocol!
USBlyzer is an easy to use software-based USB Analyzer and USB Data Traffic Sniffer for Windows, which provides a complete yet simple to understand view for monitoring and analyzing USB Host Controllers, USB Hubs and USB Devices activity.
With USBlyzer you can:
View all plugged USB devices in hierarchical auto-refreshed tree view along with detailed information about each USB device properties and their child components:
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.
Export USB descriptor hierarchy and all captured data to a file.
The detailed list can be seen on USB analysis features page.
USBlyzer is a software-based USB protocol analyzer, so you won't have to install any additional hardware or software. It runs on 32-bit and 64-bit version of Microsoft® Windows® without any compatibility issues and does not require any service pack.
USBlyzer can be successfully used for:
USB device driver development
USB hardware development
Debugging USB-related software and hardware
Exploring USB devices descriptors and properties
Capturing USB data transferred to or from the USB devices
Reverse engineering the USB protocol
Spying and analyzing the USB communications
Learning more about USB internals
Testing and troubleshooting software and hardware
