SYMPTOMS

Consider the following scenario:
  • You configure a USB webcam as the default audio device on a computer that is running Windows Vista or Windows Server 2008.
  • An application that uses the USB webcam is running on the computer.
  • The computer enters and then resumes from sleep several times.
In this scenario, you may receive one of the following Stop error messages:
0x000000A0
INTERNAL_POWER_ERROR
0x0000009F
DRIVER_POWER_STATE_FAILURE

CAUSE

This problem occurs because the operating system tries to handle the DeviceIoControl I/O request packets (IRPs) when the device is in a low power state. This behavior causes the operating system to enter an inconsistent state. Then, nonpaged Pool memory is not allocated successfully. Therefore, the Stop errors occur.

RESOLUTION

Windows Vista and Windows Server 2008 file information notes
Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.

    VersionProductSR_LevelService branch
    6.0.600 1 . 22xxxWindows Vista and Windows Server 2008SP1LDR
    6.0.600 2 . 22xxxWindows Vista and Windows Server 2008SP2LDR
  • Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxx version number.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 and for Windows Vista" section. MUM files and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
