You could blacklist the driver, e.g. put the module name in /etc/modprobe.d/blacklist-whatever.conf That will at least stop the module from being loaded, but won't stop it from being enumerated. I think there's a way for userspace to claim a particular port so that the kernel doesn't even do enumeration, but I can't remember the interface. Maybe Mathias or Alan knows?
