Developing Windows drivers for emulated USB devices (UDE)
This section describes USB emulated device (UDE) support in the Windows operating system, for developing an emulated Universal Serial Bus (USB) host controller driver and a connected virtual USB device. Both components are combined into a single KMDF driver that communicates with the Microsoft-provided USB device emulation class extension (UdeCx).
Development tools and Microsoft-provided binaries
The Windows Driver Kit (WDK) contains resources that are required for driver development, such as headers, libraries, tools, and samples.
To write a function controller driver, you need:
Architecture of UDEArchitecture: USB Device Emulation (UDE)USB host-side drivers in Windows
Writing drivers for emulated host controller and devices
Familiarize yourself with UDE objects and handles. For details on WDF objects, see Introduction to Framework Objects.
Understand the behavior of UDE, how it interacts with the client driver, and the features that the client driver is expected to implement.
