  I'm not sure if it is that simple... Maybe it is for the 
drivers/cables commonly used for cell phones, but, for example, the 
very popular USB<-->Serial adapters made by KeySpan show up like this:

    - /dev/tty.KeyUSA28X<geo>1  -- or -- /dev/cu.KeyUSA28X<geo>1
    - /dev/tty.KeyUSA28X<geo>2  -- or -- /dev/cu.KeyUSA28X<geo>2

    where <geo> is the 2 or more digit geographical name.  (e.g. "913" 
means USB bus #9, host hub port #1 and external hub port #3)

  I did find a reference to the Prolific chipset and the driver they 
have for MacOS X does, as far as I can tell, use usbserial.

  Since this is so arbitrary, depending on the vendor's driver and 
choice of text string they use when constructing the name, I'd hesitate 
to code to it, it's not quite a standard. However, if there is a choice 
that must be made to make things work properly I guess we can just punt 
and hope for the best.
