Hello,

I have with the USB cam Logitech HD Webcam Pro c910 (see:
http://wiki.freebsd.org/WebcamCompat ) different results in my two
netbooks:

EeePC 900:

kernel: r226986: Tue Nov  1 2011

$ ls -l /dev/vid*
crw-rw----  1 webcamd  webcamd  0x71 12 may 10:21 /dev/video0
crw-rw----  1 webcamd  webcamd  0x7c 12 may 10:23 /dev/video8

$ pkg_info | egrep 'webcam|cuse4|skype|linux_v4l2'
cuse4bsd-kmod-0.1.21_1 Cuse4BSD character device loopback driver for userspace
pwcview-1.4.1_3     The Video4Linux PWC webcam viewer
skype-2.1.0.81,1    P2P VoIP software
webcamd-3.0.0.2     A port of Linux USB webcam and DVB drivers into userspace

the above two devices /dev/video[0|8] are shown fine in Skype and both
are working with Skype 2.1.0.81,1; as well both devices work fine with
pwcview;

Asus Aspire One D250:

kernel: r214444: Thu Oct 28 2010

$ ls -l /dev/vid*
crw-rw-rw-  1 webcamd  webcamd    0,  94 12 may 08:10 /dev/video0
crw-rw-rw-  1 webcamd  webcamd    0, 125 12 may 10:34 /dev/video8

$ pkg_info | egrep 'webcam|cuse4|skype|linux_v4l2'
cuse4bsd-kmod-0.1.23 Cuse4BSD character device loopback driver for userspace
linux_v4l2wrapper-kmod-1.0_2 Linux compatibility layer - V4L2 ioctl handler
pwcview-1.4.1_3     The Video4Linux PWC webcam viewer
skype-2.0.0.72,1    P2P VoIP software
webcamd-3.2.0.1     A port of Linux USB webcam and DVB drivers into userspace

in this netbook in Skype only device /dev/video0 is presented and works;
with pwcview both cam are working, but /dev/video8 says:

$ pwcview -d /dev/video8
libv4lconvert: warning more framesizes then I can handle!
libv4lconvert: warning more framesizes then I can handle!

Any idea why skype is not seeing /dev/video8? Is it worth to debug this
or is it just the older Skype version?

Btw: the cam Logitech HD Webcam Pro c910 produces the best pictures I
have ever seen; in my company we use this as well for comercial
videoconferencing with Tandberg Movie.

Thanks

	matthias
