I'm using fedora 8 with kernel 2.6.23.15-137.fc8

I found docs about support in ov51x-jpeg kernel module.

I compiled and installed kernel module for ov51x-jpeg, version 1.5.6
In my xorg.xonf I have
Section "Module"
* Load******** "dri"
* Load******** "v4l"
* Load******** "extmod"


* Load******** "freetype"
* Load******** "glx"
* Load******** "GLcore"
* Load******** "type1"
* Load******** "dbe"
* Load******** "vbe"
EndSection



when I make a modprobe ov51x-jpeg I get in /var/log/messages
Feb 16 02:37:30 tekkaman kernel: usbcore: registered new interface driver ov51x
Feb 16 02:37:30 tekkaman kernel: /home/gcecchi/ov51x-jpeg-1.5.6/ov51x-jpeg-core.c: 1.5.6 : ov51x USB Camera Driver



But the camera led still remains off
the /dev/video0 device was not created automatically, but also creating it manually as
crw-rw-rw- 1 root root 81, 0 2008-02-16 02:33 /dev/video0

lsmod gives

I don't get any webcam application to work. Tried with ekiga, mplayer and skype 2.0.43 beta.


for example:
[gcecchi@tekkaman ~]$ mplayer tv:// -tv driver=v4l:width=640:height=480:device=/dev/video0
MPlayer 1.0rc2-4.1.2 (C) 2000-2007 MPlayer Team
CPU: Intel(R) Core(TM)2 Duo CPU*********** @ 3.00GHz (Family: 6, Model: 15, Stepping: 9)


CPUflags:* MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1
Compiled with runtime CPU detection.
mplayer: could not connect to socket
mplayer: No such file or directory
Failed to open LIRC support. You will not be able to use your remote control.



Playing tv://.
TV file format detected.
Selected driver: v4l
*name: Video 4 Linux input
*author: Alex Beregszaszi
*comment: under development
unable to open '/dev/video0': No such device




Exiting... (End of file)

ekiga and skype say no device found...
Any hints to get it work?
Thanks in advance,
Gianluca
