[aprssig] FTDI usb/serial devices on Mac OS X?

Has anyone used an FTDI usb to rs232 chipset on Mac OS X?

I've had good results with Keyspan adapters, but I'm looking at  
chipset solutions now.  One huge complaint I have with every vendor  
I've used so far is that the driver uses names that are either based  
on the device's location in the usb "tree" or on the sequence in  
which the driver notices the device.  The FTDI documentation  
indicates that they use the serial number of the device in the device  
special file name, so I could have a consistent name for a particular  
device no matter when or where I plug it in.
