    HP Webcam access fails with bluescreen SPUVCbv x64sys


    May be of interest to others - Just noting an issue I encountered with 2 similarly spec'd machines with upgrade to Win 10 2004

    On upgrading my HP EliteBook 8470P Win 10 Pro x64 Ver 1909 b18363.900 to W10 Ver 2004[…]
    Download / Upgrade option available and initiated manually from windows update.
    Upgrade took around 1.5hours all up with no issues encountered during the upgrade process.

    Issue:     Post upgrade testing highlighted a problem when accessing the inbuilt webcam device – ie through the Camera App and also Skype.

    Error:     Fails with bluescreen SPUVCbv x64sys and system recovers/restarts.

    Background:
    Checked and I have latest HP F.74 Rev A BIOS installed.
    Also have latest HP Webcam drivers installed (sp71853.exe).
    Downloaded and re-installed latest Webcam drivers (Universal Camera Driver from HP Website) – Issue persists
    Rolled back the driver for the Webcam device (reloads generic MS Driver dated 2006!) – Issue Resolved.

    All good but I wonder what functionality may be lost by going back to a driver that old.?

    I have sent details to Microsoft (via Feedback) and will also be logging issue with HP Support.

    Would be interested if others have encountered this issue also and any thoughts on best course of action.

    Still testing but no other issues for me identified so far with the upgrade to Ver 2004.

    Thanks!

    All Microsoft drivers are deliberately dated 2006 for driver ranking.

    When default drivers are offered by Microsoft they compete with component manufacturer drivers first by year.

    This way if available all component manufacturer drivers should be newer than Microsoft drivers and have preference.

    In case Microsoft and component manufacturer drivers match by year the next ranking is by version.

    New operating systems can become corrupt.

    Drivers are files and can become corrupt.

    To test for corruption versus incompatibility you can reinstall the driver directly from the HP website.

    If there is another BSOD then you have established cause and effect incompatibility.

    If there is no new BSOD then you had likely a corrupted driver.

    Thanks for responding zbook - some good info and specifics there.

    To me then, that would confirm it is an incompatible HP driver issue as I downloaded and installed the latest driver from HP website and the BSOD persisted. As mentioned, I have had this happen on 2 machines which helps confirm it's not just my setup. I will open a case with HP and work through it with them.

    In the meantime, hopefully the Microsoft generic 2006 driver will serve as a stable workaround (for using Skype especially).

    These are Windows 2004 known issues:
    https://docs.microsoft.com/en-us/win...indows-10-2004

    One method to report is the Microsoft feedback hub:

    Microsoft Forms


    This is additional information on default Microsoft drivers:

    @ashleyg my laptop has the same specs than yours running Windows 10 2004. I thought that the old BIOS could cause the issue then I updated it to the latest version downloaded from HP, but it didn't work. My webcam was working before updating to W10 2004, so I know for sure this release is causing the issue. Fortunately I have a copy of the previous working release so I will go back to it this weekend and I will let you know if problem was resolved.

    What model HP laptop are you using?

    I have been in discussion with HP support on this and it sounds like they are not intending to release an updated driver (at least at this stage). They referred me to this publication:

    https://support.hp.com/nz-en/document/c05195282

    Under the section 'My PC was purchased before August 2013' it says..
    HP PCs manufactured before August of 2013 might not have a complete set of hardware and/or drivers required to use all of the features in Windows 10.

    • HP is not testing or developing Windows 10 drivers for these PC products.


    They (HP Support) said the generic Microsoft driver the system rolled back to will work and support the camera I need it for which is basically skype and using the camera app.

    I have only done basic testing of the camera functionality using the rolled-back driver at this stage but it does resolve the BSOD problem and seems to work. I have not given it a thorough test with Skype etc. at this stage however.

    So, it may be that the camera does work with Ver 2004 - the fix being to roll-back the driver

    I have not heard back from Microsoft on the issue yet.

    I'm using the elitebook 8470p. You are probably right, it won't work with the latest version. I just downgraded the OS and it's working back. Check the image. I will try to upgrade to 1903 version and see what happens.

    I just upgraded the OS to 1903 and it worked. I think I will skip the 2004 for now.

    The rollback of the driver didn't work for me. Perhaps something went wrong at some point with the updates. I have upgraded to 1909 and the webcam still works.
