FIX for usbhub.sys "NOT DIGITALLY SIGNED"

Since the last windows update, all on my new HP laptop usb ports are now dysfunctional.  Device Manager shows 'USB hub root' pilot 'usbhub.sys' of microsoft corporation is not digitally signed and therefore does not not (code 52) how microsoft may be able to find the digital signature for its own driver?  Someone knows how to fix this?

Thanks for your help.  I ended up just using the system to the factory settings restore and reset the onboard computer.  In the end, I had no sound, no usb ports were working, media files would not play and windows update might isn't even check the updates.  System files more and more appeared as "unsigned", including the 2nd driver usb (usbd.sys) who initially does not have his signature.  The system was just explosive.

It seems obvious to me that something in the directories c:\windows\system32\catroot and/or catroot2 has been altered.  What I read in other forums, it is most likely due to some kind of disturbance during the last update of windows, such as a scan of virus or something, but I really don't know what happened exactly.

The only remaining problem is now a live windows error when you try to run Halo 2 that existed before that anyway.  What I see also in other forums, there is no solution for this yet, and it's a known problem with Halo 2 and Windows 7.  I'll keep following this see if something surfaces.  Ironically, I was hoping that an update of windows could just include a fix for this.  Has not happened yet, and the last update really did not improve the system. ; P

It was very disappointing, that I could not restore the system to the point just before the update.  I don't know why it failed, but everything is working now and I did a backup fresh with this default configuration, so at least if it happens again, I should be able to bring it back to that State set up, rather than all the way back to the factory.

Thanks again.

  • RealTek HD Audio driver "stdriver64.sys" not digitally signed, and update returns the message "everything is up-to-date.

    Hello

    Recently, I checked my RealTek HD Audio drivers and found that the "stdriver64.sys" driver is not digitally signed.  It can be connected to a crash problem that I have known for two weeks now, so I try to update all the drivers and see if it will solve this problem.  When I click on update drivers for RealTek HD Audio, a message returned quickly saying that all drivers are up-to-date.  But again controlled the pilot "stdriver64.sys" shows that it is not digitally signed.  Is there another way to update this driver or another way to take with this?  Thank you for your help.

    I read everything I can find on this problem. I don't have any roxio software on my machine and this driver is associated with the roxio software. This problem just started a week ago. the only program I have installed is corel photo album 6. I uninstalled the driver and then win7 reinstalls on reboot with the same problem. This is associated with a recent windows update? is there a registry fix? WTF?

    Hello

    The updates that you have installed?

    We are not sure what could have caused this problem. You can try to remove the affected filter drivers and check. This helped little.

    To do this, follow these steps:

    1. Click Start, type regedit in the search box, and then click regedit in the list programs.

    If you are prompted for an administrator password or a confirmation, type your password, or click on continue.

    2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}

    Warning There may be many instances of the registry subkey that is mentioned in step 2. You must ensure that you are in the appropriate registry subkey before modifying the UpperFilters and LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the default data value is the CD-ROM/DVD-ROM and the class data value is CDROM.

    3. in the right pane, click UpperFilters, and then click on remove.
    4. click on Yes to confirm the deletion of the UpperFilters registry entry.
    5. in the right pane, click LowerFilters, and then click on remove.
    6. click on Yes to confirm the deletion of the LowerFilters registry entry.
    7. exit the registry editor and then restart the computer.

    Note After the removal of the UpperFilters registry entry and the LowerFilters registry entry, you may lose functionality in certain programs such as CD recording programs. In this scenario, you must reinstall all of the programs involved.

  • Cannot install for photosmart d110 driver because not digitally signed

    D110 Photosmart all-in-one.  Cannot install driver after running recovory disc.

    Windows 7 64 bit Dell Inspiron 580.

    I had to run the recovery disk after receiving the virus/malware.  It seems that all the other printer drivers are on my computer.  I downloaded the driver from HP.com several times and it cannot be found by my computer.  Manually, I tried to load it from the disc supplied with the printer and got the following error message: "cannot install driver because it is not digitally signed or not signed in the appropriate way.»

    We could continue, while reinstalling Windows would finally settle the matter. If you believe that the issue is related to the virus, you can run a scan for viruses on your computer using any anti-virus software you have. After that, reinstalling Windows could be the next step.

    Alternatively, you can try to install the printer in Mode safe, if you have not already.

    If you could mark a message with the accepted Solution if I helped you, would be great!

    Please let me know what happens. Thank you!

    I really don't want to recreate the image outside

    JohnL

    Hi John,.

    Thank you for your update on the issue.

    Before a new image, I suggest you to reinstall the USB controller drivers and check the status.

    Remove and reinstall all USB controllers.

    1. Open Manager devices by clicking the Start button, click Control Panel, click system and security, and then, under System, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
    2. In the list of the categories of equipment, locate and expand Bus USB controllers.
    3. Right-click every device under the Bus USB controllers node and then click Uninstall to remove them one at a time.
    4. Restart the computer and let the USB controllers get reinstalled.

    Plug in the removable USB device and test to make sure that you do not get any problems to connect external USB devices.

    Please post back your results for assistance.

  • What fix for serscan.sys used?

    I had some difficulties to install and set up my new wireless printer.  The phase of wireless connection requires serscan.sys that is not on my computer running xp family, with a hidden recovery partition I don't know how to access, apart from reinstalling windows.

    I found the fix page that appears at this address but it lists 2 patches, one for the service pak 2, one for service pack 3.  This wouldn't be a problem, knowing that I have run service pack 3, but the download page does not list the patches according to this criterion.  the version name of single file given in the entry of the initial aid is also not used in the download page, which uses a file name for each of the 2 options.  The release of the 2 options are sp3 and sp4.

    This brings me to wonder - what patch should I download and install?

    I would appreciate an answer quickly in interest rule of my patience and composure, there will be a cookie for the first.  :-)

  • Fix for buttons/icons not rendered? Victory 8.1, Firefox 40

    Hello Fellow FF users! For the past few weeks I tried to correct certain defects, I had with my mouse and keyboard. They are now fixed and works very well, I made about 1 000 different things, including changing the settings during this process. So about 2 weeks ago, the buttons on the pages stopped rendering. Which means that, if there is no button to click, as record, or a star rating or really buttons, which now seems in their place is a small rectangular box with small letters in it (absurd) and when you click it, nothing happens. Most embarrassing! I included icons in my search because they may be related somehow, although most of them make very well.

    Sorry you guys, but this bug is driving me crazy and I couldn't find a solution anywhere online in FF or settings, etc. I'm so angry at myself for not being able to fix myself! I bet it's something silly that can easily be solved. Hope so.

    Thanks in advance for any suggestion or help that you might have.

    Kathy

    OMG! YES! That solved this problem completely, Jscher2000! Yay yay yay! She was driving me crazy! And Yes, while messing around with settings and things that the past few weeks, I had, in fact, put my own fonts for web pages and the box was checked. I'm so happy to have this problem! I can not thank you enough, Js!

    Given that Windows installed SP1 printed the last doc is not removed and blocks therefor all subsequent print jobs. Currently I have to restart the computer to get the doc "deletion" removed printing (QC) is a solution for this?

  • ATI Radeon graphics drivers digitally signed?

    I chose the 'microsoft signed driver requirement apply' at startup.

    This means graphics drivers will not be loaded?

    Hello

    Thanks for asking this question to Microsoft Community.

    I understand that you want to know if ATI Radeon graphics drivers are digitally signed.

    He would be grateful if you could answer these questions. This will help us to a better way to get a resolution of the issue.

    Why did you choose the 'apply microsoft driver signing request' on the boot option?

    If you choose this option, also the graphics card drivers will be loaded. But there will be some problems of reduced functionality. You can contact the manufacturer of the driver for further assistance.

    Microsoft has a tool implemented in Windows 7 and Vista called Sigverif.exe which helps you to identify unsigned drivers.
    one) to access, type sigverif in the search box of the start Windows menu and press on enter.
    (b) click Start. The program scans all the device drivers.
    (c) at the end of the analysis, it will list down to those who are not digitally signed.
    (d) If you want to see the list of all the drivers that have been scanned, click Advanced and select view log.
    (e) you will be able to view the log.
    (f) in order to check if your drivers are digitally signed, you can run the DirectX Diagnostic tool. To do this, type DxDiag.exe in the start search box and press ENTER. The DirectX Diagnostic tool is designed to help you troubleshoot issues related to DirectX.
