Symptoms

Consider the following scenario:

  • You have a computer that is running Windows Vista, Windows Server 2008, Windows Server 2008 R2 or Windows 7.
  • You connect a full-speed USB audio device to a high-speed hub, and then connect this hub to the root hub of a USB 2.0 EHCI host controller on the computer, OR you connect a high speed USB 2.0 audio device directly to the root hub of a USB 2.0 EHCI host controller on the computer.
  • You start an audio playback or recording program, such as Sound Recorder. This program opens the USB audio device.

In this scenario, you notice that there is high CPU usage approximately every 15 seconds on the computer. Additionally, you may experience skipping in audio playback from the audio device when overall CPU usage reaches 100%.

Cause

This problem occurs because of an issue in the usbport.sys driver.

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.

    Version Product SR_Level Service branch
    6.0.600
    1.
    22xxx
    Windows Vista and Windows Server 2008 SP1 LDR
    6.0.600
    2.
    22xxx
    Windows Vista and Windows Server 2008 SP2 LDR
  • 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.

Windows 7 and Windows Server 2008 R2 file information notes

Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" 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, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version Product Milestone Service branch
    6.1.760
    0.16xxx
    Windows 7 and Windows Server 2008 R2 RTM GDR
    6.1.760
    0.20xxx
    Windows 7 and Windows Server 2008 R2 RTM LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, extremely important issues. LDR service branches contain hotfixes in addition to widely released fixes.

  • 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 R2 and for Windows 7" section. MUM 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.
