I've got a uftdi based one, but it doesn't work on my Mac. I plug it
in and the system profiler shows that it's an unknown device. I didn't
follow up on it because I thought it just wasn't supported. I'll have
to plug it in again when I get home and compare it to what you have
here. I'm on a 10.6.6 machine, maybe something changed. You said you
didn't have to install a driver for that? I searched around and found
various 3rd party USB to serial drivers for Mac...

Have you downloaded the driver from ftdi? I've used them successfully under both MacOS and NetBSD, but you do need to install the driver on MacOS.
