On a Microsoft Windows XP-based computer, you use a high-bandwidth USB 2.0 device, such as an isochronous video camera. However, after you repeatedly start and stop the USB device, it stops working correctly. This problem is more likely to occur on a system that has 256 megabytes (MB) of RAM or less. However, when the system is under heavy stress, this problem may also occur on a system that has more than 256 MB of RAM.

When this problem occurs, you may receive an error message that resembles the following:

Creation of the video preview failed.

After this problem occurs, the USB device may be marked with a yellow exclamation point in Device Manager. Additionally, other USB 2.0 devices may not enumerate correctly, may not work correctly, or both.


This problem is caused by a bandwidth leak in the USB 2.0 bus.
