This question already has an answer here:

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?

  • Can you explain what you mean by “stranded user”? – dessert Aug 18 '17 at 13:56
  • I mean root user . – Manoj Singh Aug 18 '17 at 14:01
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)

  • every time when i give this cmd , i got a FATAL error ."modprob :FATAL :Module usb_storage is in use ". – Manoj Singh Aug 18 '17 at 14:06
  • Well do you have usb storages attached? Try to remove them first. – dessert Aug 18 '17 at 14:16
  • 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
