I'm more used to looking at /proc/bus/usb/devices than lsusb, but it looks
to me like your device has two interfaces (usb-level interfaces, that is).

The driver Greg wrote looks for a compatible interface to bind to.  The way
it specified what type of interface, both advertised interfaces qualify.

Then, it specified two serial-level interfaces for each usb-level
interface you bind to.  Thus, 4 interfaces.

I think the first thing to do is change the driver to .num_ports = 1 --
that will get you down to just 2 /dev/ttyUSB nodes.  Try that, and then see
what happens when you try to talk to the various /dev/ttyUSB nodes.

Next, we may want to think about how to talk to that control interface.
But, that's out of my expertise.  You may want to use something like
minicom (instead of kppp) to debug with.
