I searched the sources. Sources can be installed from "sysinstall" if they are
not installed already.
The interface classes are defined in "/sys/dev/usb/usb.h" (see UICLASS_XXX and
UISUBCLASS_XXX). If you type "cat /sys/dev/usb/* |more" and press enter, then
type "/UICLASS_CDC" and press enter. Then use the "n"-key to search forth and
"N"-key to search back until you find something that matches your USB
descriptors.
Then scroll up to find the file name:
__FBSDID("$FreeBSD: src/sys/dev/usb/umodem.c,v 1.57 2005/01/31 13:58:10
akiyama Exp $");
Then check if there is a module that compiles this file:
cat `find /sys/modules |grep Makefile` | more
(search for "umodem.c")
If no match try kernel configuration files:
cat /sys/conf/* | more
(search for "umodem.c")
This might not be so easy, so in the future maybe something like
"kldload /boot/kernel/usb*ko" will load all USB drivers?
