yes, you are right. The explanation is the following : As I saw the driver I 
tried to use with the webcam (and I have reports that say it does with such 
webcam) didn't create the appropriate device (video0), I thought it would 
be a good idea to add a card I had there  (the pinnacle dv500) to that 
computer and see if that could create the video device. But narda, nothing. 
So I removed the card, deleted the file 06-dvb.rules I created, and kept 
only my webcam plugs in one of the two usb entry.
So I'm back at the beginning, with the webcam which doesn't work.
