I'm playing with a built-in webcam here, a Sonix Technology Co CNF9055
with usb-ID 04f2:b1d6. This ID isn't listed in the webcamd man pages,
but the camera does work... sort of.
If I run webcamd in the foreground, about 7-8 times out of 10, I get:
# /usr/local/sbin/webcamd -d 3.3 -i 0
Attached ugen3.3[0] to cuse unit 0
Creating /dev/video0
And the video works. Cool!
But sometimes, about 25% of the time, it hangs at:
# /usr/local/sbin/webcamd -d 3.3 -i 0
Attached ugen3.3[0] to cuse unit 0
with no creation of the video device.
If I run it in the background, it fails 100% of the time:
# /usr/local/sbin/webcamd -B -d 3.3 -i 0
Attached ugen3.3[0] to cuse unit -1
#
which also means it fails to start if webcamd is started from its rc.d
script at boot time.
Webcamd version is 0.1.23, cuse is 0.1.13. System is 8.2-release amd64.

What other info can I provide to debug this?
