I added a line to the table, but it seems to have failed since I used the
VID# instead of the VID# name.  Where are the VID names mapped to the
VID#'s?  Apparently, I know enough about coding to be dangerous.  I'll do
some more digging to try to fix my own error.

Here's a diff of the original source and my modified source:

[/usr/src/sys/dev/usb/serial]$ /usr/bin/diff ./uftdi.c ./uftdi.c.ORIG
914d913
<       UFTDI_DEV(2100, 9e56, 0),
[/usr/src/sys/dev/usb/serial]$

Here's the compile splattage:

Your mind is like a parachute, it works much better when it is open.
