sorry for my bad english.
I'm under dapper (final).
I've a tv tuner card (pci) and an usb webcam.
At each boot, when webcam is connected, I can't know if this is the
tuner or the webcam who has the /dev/video0 or /dev/video1.
"dmesg" indicates pci and usb are recognized at the same time.
So when I start apps like tvtime,ekiga,camorama, I have error like "bad
device" because tv apps don't play with webcam, and ekiga don't play
with a tv tuner.
How to resolve the problem without disconnect webcam at each boot?
What system should do this?
- linux has to give the good order.
- I thought udev was able to resolve the problem. apparently not
designed to do this.
- apps have to select the good hardware when they start. (is /dev/video0
a tv tuner card? or /dev/video1? or /dev/video2...).
At this, I can't answer, so I ask you for help.
