KWorld VS-USB2800D recognized as PointNix Intra-Oral Camera - No Composite Input

["Kay Wrobel" <kwrobel@letterboxes.org>]

Hi video4linux list,

This may be something that has been asked in the past. I have a KWorld
VS-USB2800D video capture device and my Ubuntu 9.04 Jaunty recognizes it
as a PointNix Intra-Oral Camera. The only thing that works is the
S-Video input. However, I'd like to use the Composite input (regular
yellow RCA). So here's the dmesg:

[20151.927534] Em28xx: Initialized (Em28xx Audio Extension) extension

Notice how it only generates /dev/video0 and /dev/vbi0. I would have
expected to see two additional devices, like /dev/video1 and /dev/vbi1.

Maybe the detected Intra-Oral camera doesn't have that input, but the
KWorld VS-USB2008D does. What can be done to make the driver recognize
the Composite input correctly?

Thanks for any help...
