I want to disable usb mass storage on Ubuntu desktop 10.04, 11.04 and 11.10.

As security policy to avoid data leakage. But in case of emergency there easy way getting usb mass storage back.

Blacklist the usb_storage module by adding blacklist usb_storage to /etc/modprobe.d/blacklist.conf.

To load the module manually, run sudo modprobe usb_storage.

Just rename storage to storage-old:

mv /lib/modules/3.2.0-35-generic-pae/kernel/drivers/usb/storage /lib/modules/3.2.0-35-generic-pae/kernel/drivers/usb/storage-old

You must do so when the kernel version updated

This would stop working when installing kernel updates would install a new kernel with this module again – tomodachi Jul 24 '13 at 13:58

It is generally not a good idea to do modifications to files within /usr or /lib for reasons like this. Always better to modify conf files in /etc where possible. – thomasrutter Jul 24 '13 at 14:25

just rename storage to storage-old:

for me renaming as /lib/modules/3.2.0-29-generic/kernel/drivers/usb/storage-old

just didn't work , but when i created tar archive named storage-old.tar and deleted storage-old the method seems to work
