FIX: Selective Suspend Does Not Work on Video Capture Devices That Use the Stream Class Driver
This article has been archived. It is offered "as is" and will no longer be updated.
If a universal serial bus (USB) video capture device that uses the stream class driver (stream.sys) is idle, and if the system later turns off the device, the device cannot start again when its services are required. As a result, the program that is trying to use the video capture device may stop responding.
This problem was introduced in Microsoft Windows XP Service Pack 1 (SP1) as a result of a modification that was made to the stream class driver. A change was included in SP1 to prevent communications to devices that are idle. This change blocks input/output request packet (IRP) processing. However, the SP1 implementation did not take into account selective suspend functionality. Selective suspend IRPs must not be blocked in this manner.
This hotfix contains changes to the stream class driver that permits the driver to correctly process the selective suspend IRPs so that the device can start when a program requires the device to start.
