The entry's name seems to depend on FreeBSD version. I have
a 12.0 system where no additional CUSE package is installed,
and the OS-provided CUSE, enabled by

	cuse_enable="YES"

in /boot/loader.conf seems to be sufficient. Older FreeBSD
systems (probably in the era around FreeBSD 9) seemed to
require installing the "cuse4bsd-kmod" package and a different
entry name, i. e.,

	cuse4bsd_enable="YES"

in /boot/loader.conf, which recent OS versions don't seem to
require anymore.

It's a convenient way to check basic working. By the way, you
can also use this to test "video grabbers" (video to USB con-
verters) which also use webcamd as input interface.

Fron your kldstat output (seems that your MUA has distorted the
output a little, but it's still readable):

The required module is already loaded.

Correct. You should probably add the _flags according to what
you found working during interactive testing so webcamd will
start with the right device - _if_ it starts at all... ;-)

Does webcamd already run, and did it autodetect (!) the correct
USB device? Looks like it. Maybe a pleasant surprise that the
audodetection magic worked for once.

Right, that is the console message you should see.

Definitely. You now know that it _basically_ works, so it's
probably just a matter of client program configuration.

Maybe those should be declared as runtime dependencies and
then automatically installed by pkg?

Great to see you got it working! :-)
