Universal Serial Bus (USB) provides an expandable, hot-pluggable Plug and Play serial interface that ensures a standard, low-cost connection for peripheral devices such as keyboards, mice, joysticks, printers, scanners, storage devices, modems, and video conferencing cameras. Migration to USB is recommended for all peripheral devices that use legacy ports such as PS/2, serial, and parallel ports.
The USB-IF is a Special Interest Groups (SIGs) that maintains the Official USB Specification, test specifications and tools.
Windows operating systems include native support for USB host controllers, hubs, and devices and systems that comply with the official USB specification. Windows also provides programming interfaces that you can use to develop device drivers and applications that communicate with a USB device.

Testing USB devices with Windows
Host controller and hub drivers - USB driver stack
Microsoft provides a core stack of drivers that interoperate with devices that are connected to EHCI and xHCI controllers.
USB-IF device class drivers
Windows provides in-box device class drivers for many USB-IF approvide device classes, audio, mass storage, and so on.
USB generic function driver–WinUSB
Windows provides Winusb.sys that can be loaded as a function driver for a custom device and a function of a composite device.
USB generic parent driver for composite devices–Usbccgp
Parent driver for USB devices with multiple functions. Usbccgp creates physical device objects (PDOs) for each of those functions. Those individual PDOs are managed by their respective USB function drivers, which could be the Winusb.sys driver or a USB device class driver.
Testing USB hardware, drivers, and apps in Windows
Get information about the tools that you can use to test your USB hardware or software, capture traces of operations and other system events, and observe how the USB driver stack responds to a request sent by a client driver or an application.
Read an overview of tests in the Hardware Certification Kit that enable hardware vendors and device manufacturers to prepare their USB devices and host controllers for Windows Hardware Certification submission.

provide automated testing that can be used during the development cycle of USB controllers, devices and systems, especially stress testing.
- OSR USB FX2 Learning Kit
If you are new to USB driver development. The kit is the most suitable to study USB samples included in this documentation set. You can get the learning kit from OSR Online Store.
Common USB scenarios
1—Get the device handle for communication and use the retrieved handle or object to send data transfers.
USB descriptor retrieval to get information about the device's configuration(s), interface(s), setting(s), and their endpoint(s).
2—Configure the device to select an active USB configuration and setting per interface.
3—Send control transfers for configuring the device and performing vendor commands that are specific to particular device.
4—Send bulk transfers, typically used by mass storage devices that transfer large amount of data.
5—Send interrupt transfers. Data is read to retrieve hardware interrupt data.
6—Send isochronous transfers, mostly used for media streaming devices.
7—USB selective suspend to allow the device to enter a low power state and bring the device back to working state.
