Modem creation/startup order

I've got two ports whitelisted for use by MM. What determines which one of
them will be 'Modem/0' ?

Is there a way to get MM to create/initialise 0 first, then 1 - as opposed
to doing both in *parallel*?


I'm getting MM to use the Cinterion plugin for my modem, by adding 


to the udev rule (the port is a tty); together with mods to the plugin code,
to set its MM_PLUGIN_ALLOWED_DRIVERS to the modem's driver name.

However it's also deciding to also try 3 other plugins (as well as Generic)
- Via, Iridium, Nokia.  It's not a major problem because it does try
Cinterion first, and decide it's the best one. But why the other candidates?
