I've long ago stopped using 8.04... Try downloading the source for
libftdi. Set the prefix to /usr/local and make, make install it. That
version will override the one in Ubuntu without disrupting your
up-to-date process.

There was a big rewrite in all of these tools around that time when
they switched from the old libusb to the new one.

It could also be a problem in the kernel driver for the 2232H chip.
The old driver may not know about the newer model chip.

It's a lot easy to just upgrade your Ubuntu.
