You Do Not Have Permission To Access This Device

Hello, I am having an issue that I have been working on for weeks now and have been unable to find a solution.

It seems out of the blue, my computer has denied me permission to access any and all removable media through usb. All my thumb-drives, all my sd-readers, and two phones. I always get this window:



I have tried putting ownership to my user account, with admin status, and I get this window:



When I click Yes:


When No is clicked:


I tried to edit options in the group policy editor, but "removable media" is not an option.

I tried to take ownership using elevated console commands, and no success, it wont even let me run chkdsk on the drive. (also changed drive letter with no success)

When I go into disk manager, any device I try to access is listed as healthy, my usb drives all have correct space remaining and are FAT32, and not to mention when my devices are plugged into another pc, there is no issue accessing them, so I think its down to my computer.

One last thing, out of nowhere, uninstalling my usb root hub through device manager and restarting the pc allowed me to access the drives and phones for a very short period of time, then the same issues arose once again and uninstalling/reinstalling the root hub never solved the issue again.

Sorry for the novel it's just been killing me that I can't get this to work. I know it's probably something stupid simple that I am overthinking or overlooking, any help would be greatly appreciated.

Have you given full permissions to Everyone user group like so:

Make sure to open the Command Prompt as a administrator.

Code:

Icacls E:\  /grant Everyone:F

Thanks for the reply FreeBooter.

I have tried that in the past and it has not worked, I tried it again and get this:

Follow the instructions, and you should then be able to click on whatever it is and it should work. Be forewarned that it looks like things have gone crazy . . . just wait until it settles down and disappears, then try clicking on your file.

Thanks for the reply, Wynona.

I have tried this as well in the past, the issue is my removable drives are not accessible at all, and this only adds the take ownership option to files and folders, not drives. I cannot even open removable drives to take ownership of a file or folder inside of it.

Unless there is a step i am missing, still no luck, Thanks for the help, any more suggestions would be greatly appreciated.

When right clicking a file on C:


When right clicking on in-accessible drive:


There are two options because i have tried two different scripts. Removed both, tried the one in suggested in this forum, and have received the same results.

Since the problem occurs across multiple devices all of which are of device class Disk, makes me suspect (or at least want to check) driver filters applied to Device class = DISK.

I noticed that my computer never installed the windows update from October. As I was out of any other ideas, I ran the update and now my drives are accessible. I think something was wrong with the usb 3.0 ports not being able to properly accomodate 2.0 devices (my usb drives are 2.0) because the usb troubleshooter has told me this before but with no issues accessing the drives. Thanks to all the helpful posts, It seems this issue is resolved for now, and something as simple as windows update corrected it (update has caused more issues for me in the past than it has solved)

Thanks!

only a few hours later, no changes made and my removable devices are back to no access...this is extremely frustrating. There is clearly something wonky with the usb controller or something, my drives still work fine on other pc's.
