Have you got the video 4 Linux drivers in? Check with lsmod if not, insmod
videodev.

Got this
root@xxxxxxx:/home/akm/sm > lsmod
Module                  Size  Used by
mod_quickcam           28768   0  (unused)
videodev                4992   0  [mod_quickcam]

So I can't load another module of the same name.  

/dev/video was already pointing to /dev/video0   but I may not have had 
sufificent permissions.  Now read for everyone.


root@xxxxxxx:/home/akm/sm > xawtv
This is xawtv-3.43, running on Linux/i686 (2.4.4-64GB-SMP)
x11: 1024x768, 16 bit/pixel, 2048 byte/scanline, DGA
can't open /dev/video: No such device
v4l-conf had some trouble, trying to continue anyway
open /dev/video: No such device
v4l: open /dev/video: No such device
no video grabber device available

# man xawtv 
# man v4l
         not v helpful

it is /dev/video that I am tripping up on, and I'm not sure what it is that I 
don't know.
How can I determine which device _file_ is actually connected to the USB port?
Clearly something can talk to that physical port, since the usbview program 
can see the camera.
