USB port storage not working


Hello everybody,
I have a strength problem with my USB port, it's totally not work.
I try to change "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor"


But an error message appears:

"Error Editing Value
Cannot edit Start: Error writing the value's new contents.

I also give permissions full control to these files "UsbStor.pnf"

And I create new key in the registry:



All of that doesn't solve the problem.

Please, I really need your help.


Finally, I got the solution.



right-click on USBSTOR permissions - advanced - add -
Enter the object name "select a logged-on user"
Allow Full Control

Now try to change:

"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor" "Start=3"
