I do not know about that wireless device in special, but I do know something about modules
Concerning the modules, the commands you posted seem a bit confusing, as they first remove the module "b43" and then load it again:
sudo modprobe -r b43 ssb
#this removes (-r) the modules "b43" and "ssb" if they are already loaded (see *man modprobe*)
sudo modprobe b43
#this loads the module "b43"
To load a module at boot time, add the module-name to the end of the file /etc/modules (you can edit the file executing sudo gedit /etc/modules
, for more info see man modules and man modprobe)
To explicitly prevent loading a module at boot time, you can blacklist it, by adding the module-name to the end of the file /etc/modprobe.d/blacklist.conf
So maybe in your case, it could be enough to add "ssb" into /etc/modprobe.d/blacklist.conf
Try it out and share with us :)
