Access Denied problem still not fixed - Win 7 - Adding new USB drivers (Solved)

(1/3) > >>

Paratron:
About 7 days ago, Windows 7 quit loading drivers for any newly connected UDB device.  USB devices that have been connected before that date continue to work properly and are recognized by Windows 7.  Flash drives and external drive enclosures that have not been connected before fail to be recognized by Windows 7 in Computer or Disk Management and are identified in Device Manager wit a warning icon.  Driver Updates find a driver but give the Access Denied error message.  I am logged in as Administrator.  This is a local machine, not connected to any network.  I downloaded Tweaking.com, disconnected from the internet and shut off the antivirus software.  I restarted the computer and went completely through the Tweaking.com steps, including all the ckdsk options, etc.  I had Tweaking.com review and reset everything, checking the box "select all" so all permissions should have been restored by Tweaking.  Each time when I finished, the Access Denied error message remained unresolved.  Additionally, Windows & fails to restore, to any set point, this also was the case both before and after running Tweaking.  Now, after the tweaking, it's taking far longer for the computer to boot, and the machine seems much slower overall.  I'm attaching a copy of the error message.  Computer:  HP DV7-3080us Entertainment Notebook, HP installed Windows 7 Professional 64-bit, Intel Core i7 processor, 6gig RAM, 500gig hard drive.  Thanks for any help and suggestions.  Sincerely, Doug

That error normally has to do with registry permissions.

Which my Windows Repair should have fixed, IF it was able to set the permissions. The registry permissions are ran under the system account, so normally it does unless the permissions are corrupted.

So check this for me


--- Quote ---    Run regedit from the Start menu.
    Navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ENUM\USB using the tree to expand folders.
    Right Click the USB folder and select Permissions...
    In the dialog box, verify Everyone is a listed group and that Read is checked.
    Click the Advanced tab and make sure Include inheritable permissions from this object's parent is selected as shown.

    Navigate to the Owner tab and make sure Replace owner on subcontainers and objects is selected as shown.

    Select Apply to apply these changes. A warning message may appear at this point. Select OK to continue.
    Select Apply in the Permissions for USB dialog box if necessary, then select OK to exit.
    Retry the installation.

Let me know if you see anything odd in the permissions for that key. Also as another test, create a new user account and login with it and try the usb, just as a test. That will tell me if it is a permissions problem in the hkey_current_user or not :wink:

Oh, and make sure the UAC is turned off as well. Seen problems with the UAC before.

Shane,

Although I am a Mechanical Engineer, I am not abundantly familiar with things you computer techies talk about.  So I humbly ask...

How do you log in to the "System Account"? (Windows 7 Professional)  I am logged in as "administrator"  Please give me step by step instructions please.

What is the "UAC" and how do you turn it off?

My USB folder has hundreds of files.  Is there a global permission upgrade I can make that resets permissions in all of them or must I open and change each file manually in regedit?

Thanks for your help and patience and I will report back when I execute your next set of suggestions.

Also, remember my Windows 7 Professional will also no longer restore to any previous restore point.  It goes through the process and then upon reboot gives the "Restore Failed" message and then goes through the long process of reverting forward back to it's original condition.  The Access Denied errors I am getting and the failure to restore are probably related to the same issue and it would seem there is a deep problem somewhere in my Windows 7 Professional program.

Sincerely, Doug

Hi, You could try to download the drivers from the manufactureres web site for your usb device. This may sometime solve the issue.

Hi,
                   I also suppose that your computer might be infected with malware
                    Please scan your computer with malware bytes and see whether your restore point problem goes.If something is preventing from install, it is pure malware attack.
