  1. How to Block USB Storage Devices in Linux

  2. Identify the device driver For this purpose, we will use lsmod command. It will list all device drivers loaded in kernel. But its output can be really long so we pass it through grep command and search for ‘usb_storage’ to get the line pertaining to USB devices. # lsmod | grep usb_storage

  3. List the content of current runtime kernel USB storage # ls /lib/modules/`uname -r`/kernel/drivers/usb/storage/

  4. Block USB storage module from loading into kernel RHEL/CentOS/Fedora # cd /lib/modules/`uname -r`/kernel/drivers/usb/storage/ # ls # mv usb-storage.ko.xz usb-storage.ko.xz.blacklist Ubuntu/Debian $ cd /lib/modules/`uname -r`/kernel/drivers/usb/storage/ $ ls $ mv usb-storage.ko usb-storage.ko.blacklist

  5. Unblock USB storage If you want to undo the above changes, just run the following commands. # cd /lib/modules/`uname -r`/kernel/drivers/usb/storage/ # mv usb-storage.ko.xz.blacklist usb-storage.ko.xz
