I'm really starting to ask - "has this thing even been tested!?!?!"
I plug the Overo adapter boards into the USB console and upon plugging
another one in, it seems as though the USB thinks as though I'm plugging in
a different board all together...
So, I have to reinstall the drivers every time I plug a new adapter card
into the USB.

This is a function of the operating system you are using on the host
computer. I'm guessing it's Windows (as nothing else requires such
blatant driver installation), and I'll share my own experience with
Windows: Even plugging the same device into a new USB port requires
the reinstallation of the same driver; and plugging the same device
with a different serial number or product ID (in the case of a
reflashing) obviously will cause windows to install the driver again.
It's got nothing to do with the Gumstix itself, but I'm sure that each
individual adapter board containing an FT232* is such that it has
identifying characteristics that cause windows to think it necessary
to reinstall the drivers.
As such, you can easily end up with 30 extra "COM" ports based solely
on USB<->Serial converters plugged in to different USB ports at
This should not be considered a flaw in the Gumstix.
