TI 3410 USB-to-serial: what did we do to our kernel to make it work?

I have a Multitech Multimodem ZBA that uses the TI 3410 chipset to basically turn this serial modem into a USB one.  It works perfectly with our kernel with no configuration.  Ubuntu, on the other hand, doesn't do anything at all when I hotplug it.  I put all the firmware from our /lib/firmware that is related to the modem in the Ubuntu /lib/firmware, tried creating udev rules, blah blah, and it never seems to come to life.  So what is so special about our kernel that lets this modem, or technically, this TI chipset, work?  Is there a patch that I am not aware of?

Here is all the information about this modem while plugged into Arch.

Re: TI 3410 USB-to-serial: what did we do to our kernel to make it work?

Maybe arch does have an extra udev rule for that device, no other ideas here.
