Post subject:  video4linux device assignment ???

Hi ...

I have a little problem ... with my mythbox ... I have to change my tv cards on old analog tv / dvb.t card changed to a dual pvr-500 :-) but now the video devices have changed (video0 -> video1 / video2 ... my second card a siemens dvb-c / analog got now video0 ...

but sometimes I connect a little usb webcam which the gets video1 and dual tuner card get video 2 / 3 ... :-( ... this happens only if usb webcam is connected at boottime ... if I attach it after boot it will get video3 device !

Is it possible to rename this devices by hotplug like eth sometimes did when there is a lan / wlan connection?

Is it a v4l problem?

Thanks
Martin

It's actually a hotplug subsytem called UDEV, if you follow these threads here and here. It's recommended that you read the whole way through as it appears the best way is create known symlinks to the devices rather than trying to force a specific /dev/videoN.
