Humm, maybe I'm way off here, but don't you want to use the GSPCA 
USB/Webcam driver?  But you are using a kworld composite to USB adaptor. 
  Ok, maybe not.

But, I've got to ask - why the combo (coax camera & coax->usb/adaptor)?

You can buy 10BaseT internet cameras for prob ~$50 and wireless versions 
for prob ~$80 on sale.  I was doing this w/zoneMinder for a while.  Been 
thinking of putting it back on line recently.  W/Ethernet, you can place 
cameras a good distance from the computer.  W/USB you are limited w/o 
USB extension hardware.

USB cameras are also tricky.  The support is there for common chip sets. 
  But I don't know about the kworld usb device.  When I plug a USB 
camera into my Debian / mythtv system, it shows up as a 
/dev/video<something>.  Unfortunately this messes w/the TV tuner cards 
and breaks the mythtv / back end feature.

I don't remember any of these problems while using wireless or cabled 
Ethernet cameras.  At the time I was more concerned I wasn't getting the 
results from zoneMinder I had expected (false triggering or triggering 
due to wind blowing trees around).

Alternatively (I was looking into this as well) I was thinking of 
creating a cluster of low cost USB cameras in remote locations and using 
something like a NSLU2 (correct name? a.k.a. SLUG) to manage and bridge 
the camera cluster onto my 10BaseT network.  I had thought seriously 
about this as I think a 3 USB camera cluster + used SLUG would not 
exceed the cost of 1 wireless 802.11b camera.

Let us know how it goes...
