Description:

The computer stops responding when an USB device resumes from the USB Selective Suspend state in Windows 7 or in Windows Server 2008 R2.
Symptoms: You enable the USB Selective Suspend feature on a computer that is running Windows 7 or Windows Server 2008 R2. Then, the computer stops responding when one or more of the following conditions are true: - The computer enters the Sleep or Hibernate state. - One or more USB devices resumes from an idle state after a period of inactivity. Cause: The update resolves an issue that occurs when a connected USB device exits the USB selective suspend state, and the USB hub incorrectly reports that the device is disconnected from the USB hub port. This incorrect status report may be caused by a hardware error in the USB hub or connected USB device. Then, the Microsoft USB Hub driver (Usbhub.sys) incorrectly tries to get a spin lock that has already been received in the same thread. This causes a kernel mode deadlock. Therefore, the computer stops responding. Install this update to resolve issues in Windows. For a complete listing of the issues that are included in this update, see the associated Microsoft Knowledge Base article for more information. After you install this item, you may have to restart your computer. |
