[PLUG] V4L Maximum video devices?

[jazzman@exdomain.org]

Is anyone familiar with V4l stuff?

You may recall I was tinkering around with various cameras and such. Well 
I managed to get my hands on a few (3 to be exact) Quickcam Express 
cameras. THere is a quickcam driver (QC-USB) and that works great. The 
original configuration I had was FC5 with 2 of the cameras. Everything 
worked great. The moment I plugged a 3rd camera in one of the first 2 
stopped working (it always seems to be /dev/video1). Any attempts to use 
that camera hang the process calling the driver to the point where I can't 
even rmmod the quickcam driver. I kill the processes opening the driver, 
but the driver still has references to it. The only way to clear it up 
appears to be to reboot.

So it appears there is a 2 camera limit somewhere (intentional or not). 
Does anyone have any insights as to whether this is a kernel limitation or 
a driver limitation? I don't have any other cameras that really work with 
Linux (I don't think... this brings up some interesting questions actually 
about which cameras I have work... but that's tinkering for another day).

Anyone have any ideas?

Thanks for the insight,

Marc
