I didn't modify any of webcamd's flags in the rc.conf* files.  You will
also have to restart devd(8) ('/etc/rc.d/devd restart') to pick up the
change to /usr/local/etc/devd/webcamd.conf.

Do you see an instance of webcamd(8) running for your touchscreen?  Is
there a /dev/input/event* device node?

I'm running my own spin of xorg-server/config/devd.c, different from the
proposed patch to x11-servers/xorg-server, but that really shouldn't be
the reason for your difficulty.
