User-Mode Driver Framework version 1.11 update for Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2

The User-Mode Driver Framework (UMDF) version 1.11 update contains the following changes:

• Adds the following driver-supplied callback interfaces and event callback functions:
  • IPnpCallbackHardware2
  • IPnpCallbackHardwareInterrupt
• Adds the following framework-supplied interfaces:
  • IWDFCmResourceList
  • IWDFDevice3
  • IWDFFile3
  • IWDFInterrupt
  • IWDFIoRequest3
  • IWDFUnifiedPropertyStore
  • IWDFUnifiedPropertyStoreFactory
  • IWDFWorkItem
• Adds the following functionality to UMDF-based drivers:
  • Accessing Hardware and Handling interrupts
  • Using Device Pooling in UMDF Drivers
  • Adds the UmdfHostProcessSharing, UmdfDirectHardwareAccess, UmdfRegisterAccessMode, UmdfFileObjectPolicy, and UmdfFsContextUsePolicy directives that are described in Specifying WDF Directives in INF files.
  • Adds well-known security identifiers (SID) for UMDF drivers
  • Adds the Unified property store support, that is described in Using the Registry in UMDF-based Drivers
  • The IoGetDeviceObjectPointer routine is integrated to work with UMDF. In earlier versions, the routine closes the handle to the device object unexpectedly, after it takes a reference on the device’s handle. Therefore, the cleanup request on the device object does not occur until all I/O is completed
  • Creates UMDF-based HID Minidrivers
  • Improves support for Supporting Idle Power-Down in UMDF-based drivers. The framework can now put the device in the D3cold power state when the idle time-out period expires. The framework can also cause the device to return to its working (D0) state when the system returns to its working (S0) state.
  • Adds the WudfVhidmini and NetNfpProvider samples
