    Hi All,

    We are writing a NDIS - WDM Driver for one of our Usb-Ethernet devices. In
    some cases we do Cancellation of all IRPs pending with the USBD. After Doing
    a IoCancelIrp, sometimes the Completion routine is not getting called on
    BulkOut Endpoint. The Completion Routine is Set to be called on all
    conditions (Success, Cancellation & Error).

    Can you help us in debugging/knowing more about this Issue ?
