USB port storage not working




Issue


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"

"Start=3"

But an error message appears:

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

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

And I create new key in the registry:

"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies"

"WriteProtect=1"

All of that doesn't solve the problem.

Please, I really need your help.

Solution


Finally, I got the solution.

start\run\regedit:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\USBSTOR

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

Now try to change:

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