Conversely, the controller can operate in the host role when connected to USB peripherals like storage drives, keyboard, mice. In that scenario, the controller on the device operates in the function role. A mobile device can behave as a peripheral when it is connected to a PC, allowing you to transfer files between your PC and the mobile device. These controllers are common on mobile devices and allow for connections to PCs, as well as USB peripherals like keyboards and mice.

Programming Guideĭeveloping Windows client drivers for USB devices. A client driver that calls these routines can run on Windows Vista and later versions of Windows. The library gets loaded and statically linked to the client driver module when it is built. These functions are defined in Usbdlib.h and the client driver requires the Usbdex.lib library. Common USB client driver referenceĪ Windows Driver Model (WDM)-based USB client driver can call functions to communicate with the Microsoft-provided USB driver stack.

These include export functions that the drivers can call, callback routines that the driver can implement, I/O requests that the driver can send to the Microsoft-provided USB driver stack, and various data structures that are used in those requests.įor the programming guide, see Universal Serial Bus (USB). The programming interfaces are used for developing drivers that interact with USB devices, host controllers, connectors. This reference section describes the driver programming interfaces that are included in the Windows Driver Kit (WDK).
