IEEE 1394 Async Receive Response not sent using Pre-Notification

View products that this article applies to.

Symptoms

When developing an IEEE client driver that receives asynchronous I/O request packets on the IEEE 1394 bus, using the Pre-Notification mechanism described in the Windows Driver Kit for such operations, asynchronous response packets may not be sent in reponse to asynchronous I/O request packets received on the IEEE 1394 bus.

This problem may be observed on Microsoft Windows versions prior to Windows 7 using the Legacy 1394 bus driver.

Cause

This problem is caused by errors in the Microsoft Windows Legacy 1394 bus driver when reponding to asynchronous I/O request packets received on the IEEE 1394 bus. These errors occur when the receiving 1394 client driver uses the Pre-Notification method for receiving asynchronous I/O request packets, as compared to the Post-Notification or No-Notification methods.

Resolution

This problem is resolved in the 1394 bus driver that is included in Microsoft Windows 7 and later versions.

For IEEE 1394 client drivers that must operate correctly on earlier versions of Windows, it is possible to work around this problem by using other asynchronous receive notification options such as Post-Notification or No Notification.
