I follow the steps below and value is 3. What else I should do/check? Thanks!

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

Hi Friend,

value 3 is for enable & value 4 is for disable the usb drive.
To disable thre drive give value 4.

If this method doesn't work for you, you can try going into device manager and under USB controllers you can try disabling them from there.

If neither of those methods work then go into your computer BIOS and disable the USB ports.
