I want to disable USB access to root and enable it when it is required.
I need to restrict users to copy and paste anything using external drives.
Can anyone help me on this?

modprobe -r usb-storage
will remove the usb-storage module and thus disable every usb storage device on the system.
To disable usb storage devices permanently, blacklist the module with
echo "blacklist usb-storage" | sudo tee -a /etc/modprobe.d/blacklist.conf
(see here)

If you also want to block it for root users, just rip out every usb slot not in use, this will block it for sure. ;) – dessert Aug 18 '17 at 14:23
