I have a Multiseat machine and the second seat has USB access from a signle port by HUB (a Keyboard and a mouse are connected to it).I need make all storages drives that is connected to to this HUB be read-only.This seat logins only by one user account.  How can I make a USB port read-only for one Account or one port (without makeing problem for Input devices that are connected it that port)?  I'm using Ubuntu 12.04Thanks
