Hi All,
Can anyone tell me, how do I disable usb storage in linux? I want just to disable usb storage, but usb keyboard / mouse should work in system.

1. Remove any references to USB device (usually /dev/sdXY - check the output from dmesg while attaching USB device) from /etc/fstab. 2. Remove any sudo or root access for the user.
That should be the easiest way i guess.

Might as well blacklist the usb_storage module.

I guess it could be done with HAL policy also (as long users do not have root access to the OS).

How do I do it with HAL policy?
As per Anurag, I checked it for dev/sdXY, which is showing me as /dev/sdb1. How do I block /dev/sdb1 to the users, what if the device picked up other sdbX as /dev/sdb1 is not available?
I also checked in /etc/fstab but could not found any relevant entry in it. FYI - The users does not have admin privileges. It is just a standard linux desktop user.
any go ahed?

If you have already commented out the devices your system assigns to usb disks - then you should be good to go. From what i know of the distros i've used, only a root/admin user can pick up arbitrary devices (which are not referenced in /etc/fstab) and mount them. Normal users cannot.

With recent distros, you can use udev. For a start: http://www.reactivated.net/writing_udev_rules.html
Check udev.rules file (in /etc/udev/ in Debian, for example), or you can change the permissions in permissions.rules file. Just look for "usb" entries in these files.

As Mrugesh suggested, knock out the usb_storage module. You will find it using the lsmod command. You will find the man pages of lsmod and modprobe interesting.

Some motherboard CMOS setups support this individual option. Check your CMOS setup.

Log into Gnome. System -> Administration -> Users and Groups
Click on the user -> Properties -> Privileges.
Uncheck -> Access external storage devices automatically.
That should do it.
