RequestForUrbXrb rule (kmdf)

  • Article

If the client driver calls WdfUsbTargetDeviceCreateWithParameters and specifies the client contract version USBD_CLIENT_CONTRACT_VERSION_602 in the WDF_USB_DEVICE_CREATE_CONFIG structure (to use the new capabilities of the USB driver stack for Windows 8), DDIs that use a URB internally would only use URB context if any of the following preconditions apply:

  • Request parameter has the Wdf device in its parent object tree.
  • Request is represented via the I/O queue.
  • Request has another I/O queue represented request in its parent object tree.

Driver model: KMDF

How to test

At compile time

Run Static Driver Verifier and specify the RequestForUrbXrb rule.

Use the following steps to run an analysis of your code:
  1. Prepare your code (use role type declarations).
  2. Run Static Driver Verifier.
  3. View and analyze the results.
