[jitter] adressing several unibrain fire-i cameras

Hello List!.
I have to grab videos from 4 unibrain’s fire-I cameras at the same time - record to HD - Playback the videos recorded. I have no problem grabbing the 4 video streams in easy chain mode. 
But what I also need is to recognize each fire-I camera and assign them a name so that I never lose track of which image is given by which camera. 
Right now I only find jamie jewett comments in a forum’s thread (2004): «… you can give each camera a unique name that stays linked to the serial number of the camera -and thus you can easily know which camera you are addressing…». 
I have done this using the Fire I Application for Windows XP (Camera 1, Camera 2...). But I don’t know how to address them in jitter (using jit.qt.grab or jit.dx.grab). The «vdevice» message uses integers and the «get vdevice» gives me Unibrain Fire-i driver / Unibrain Fire-I for each camera (as in the Windows's device manager). I’m also interested in doing the same operation in OSX with the IOXperts drivers.
So the questions should be:
How can I name and address each fire-I cameras in jitter on Windows XP?.
How can I name and address each fire-I cameras in jitter on OSX?.
What drivers are best in Windows XP? And in OSX?

Many Thanks,
Felix
