usb_storage is giving me troubles under 10.1 so I'd like to prevent the system from loading the module completely since I don't need it. How do I accomplish this?

I've got a file here (10.2) called 'modules.unsupported' under /lib/modules/2.6.18.2-34-default/

It looks to me like it's just one big module blacklist (last seven lines from mine):

blacklist affs blacklist adfs

For the mailing list, since I don't know myself: Is this is the new method for blacklisting troublesome modules?

Edit /etc/modprobe.conf.local and add the line

install usb_storage /bin/true

It sounds backwards, but it will prevent use_storage from loading

Hi Anders,

Is this because doing so 'reserves' the module for user space?

Hm, not sure what you mean by that. The "install" directive tells modprobe what to do when loading the module. If you don't have an "install", it will simply go ahead and load it. If you have one, it will run those commands *instead* of loading it. You could for example use it to run other commands before the module is loaded, for example install foo cmd1; cmd2; modprobe --ignore-install foo this will run the commands cmd1 and cmd2, and then load the module (the --ignore-install is so there isn't a perpetual loop) In the case above, with /bin/true, it will simply run /bin/true instead of loading the module, and nothing else. /bin/false would sound more logical to a human, but it returns "false" on exit, so modprobe thinks there was an error, and this would interrupt a boot, and/or give annoying error messages in the log -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

This is what we implement in Finance dept so that users cannot copy data out of the PC using any USB storage device: /etc/modprobe.conf: install usb_storage \ wall "Sorry, no USB storage devices are allowed" \ && /bin/false Make sure we reboot the PC before it takes effect, or unload the module manually: modprobe -r usb_storage HTH, -- Fajar Priyanto | Reg'd Linux User #327841 | Linux tutorial http://linux2.arinet.org 3:46pm up 2:35, 2.6.16.21-0.8-default GNU/Linux Let's use OpenOffice. http://www.openoffice.org

But then you'll get error messages. /bin/true gives the same effect but without error messages -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
