This is really nice and simple — thought all along that disabling USB ports is complex!

Admin is using Symantec Endpoint Protection to Disable the USB devices on my system. How do i enable Pendrive access?

editing the registry does not help, as symantec blocks access to pendrive after the computer detects it. Please help on how to deactivate symantec endpoint protection.

Note: I have adminstrator rights on my PC, but certain settings of symantec endpoint protection cannot be changed

Well, the admin wont come to know if they are not monitoring every USB port / every computer. What can actually happen is that every time you reboot the computer, the changes might get overwritten owing to group policy.

To disable the access to USB port, in windows XP and 2000, follow the steps below
1. Click Start, and then click Run.
2. In the Open box, type regedit, and then click OK.
3. Locate, and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor
4. In the right pane, double-click Start.
5. In the Value data box, type 4, click Hexadecimal (if it is not already selected), and then click OK.
6. Quit Registry Editor.

To re-enable a disabled port, follow these steps below

1. Click Start, and then click Run.
2. In the Open box, type regedit, and then click OK.
3. Locate, and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor
4. In the right pane, double-click Start.
5. In the Value data box, type 3, click Hexadecimal (if it is not already selected), and then click OK.
6. Quit Registry Editor.

if we follow the above mentioned steps.. will our admin in a company get to know that ????

Hi Manish,
Check if other USB controllers are active. Use Device Manager on your computer to check the status of other USB controllers.
