Question USB Webcam is not working


I have Fedora Core 1 installed and would like to use my webcam, please let me know what suggestions you have. I have tried to run xawtv but I get the :
open /dev/video0: No such device

If I run lsusb, I can see that camera has been found :

Bus 002 Device 005: 040a:0001 Kodak DVC-323

What am I missing ?

Please help !

Fedora Core 1(2.4.22-1.2115)

Did you get a installation cd with your webcam? Try using that.

If there isn't anything for Linux on the installation cd, then The camera might not be campatible with Linux...

Seems like you are missing some kernel modules. v4l is a kernel module for video for linux. In addition to this one you made need a module that drives your webcam. I use mod_quickcam for my Logitech quickcam. Do an lsmod command from the console and see if you have either of these modules. If not, search around on google for 'webcam linux' and you'll find some help yo set them up.

cheers nirvanix,

im using a kernel 2.4.22 (the one included with slackware 9.1)
i have activated the v4l modules and recompiled the kernel and all went ok
when i do a : modprobe pwc it seems to be ok and a : cat /var/log/messages dont show any error

but when i run a : xawtv , it tells me that it can't open /dev/video0 , no such device

i forgot to say that i have both videodev and pwc with lsmod

cheers for any other informations

I have this problem with my logitech pro 4000 also, do a search on google for linux webcams, some the logitech cams are not supported, also my cam has problems with the xawtv thing

But when I go to a with flash or marcomedia and right click on the flash area, to adjust macromedia settings, then select you webcam to adjust or select which webcam you are using, and the video comes up fine for me, but not with xawtv for some reason,

I also had no detection at all with the logitech quickcam, and could not find any support of drivers for the item for linux, so I took it back and got a logitec pro.

FYI not sure if anything has changed since I bought mine but that is where I was at with webcams anyhow.
