What the card needs (as seen in the linux code) is the correct
"poking" (aka: sending the right init stuff), to make it show the serial
ports. I've not looked at this on FreeBSD, just on OpenBSD. On OpenBSD
I hooked it up to the umsm(4) driver, (since that is the most simple
USB-serial driver we've got) and added the poking. It works, I can dial.
However, sometimes the device starts resetting itself, instead of dialing,
so what I have is not yet perfect ;)
