V4L Loaded or not?

[svenkatesan]

Hi
I am trying to work on my webcam.The problem is spca5xx recent one compiled without error but when I wanted check whether my v4l loaded during boot or not
"modprobe v4l" in console returns as v4l not found.
Iam in FC3-Kernel 2.6.12.....
My webcam Product and vendor Ids 0778 & 0773 respectively.
Any suggestion to load this module during boot?
Thanks

try modprobe v4l1-compat,
you also need to add it to the modprobe.conf;
here's mine:
...alias usb-controller ehci-hcd
...alias spca spca5xx

Hi drpt
Thanks for the reply.Let me try it out when I go back home.

Hi drpt
when I "modprobe v4l1-compat"------returns nothing(I mean no error)Pl refer my screen shot.
moreover "gedit modprobe.conf" opens the file--which is empty
could u please tell me what should I put in this file?
Thanks

[drpt]

gedit /etc/modprobe.conf
here is mine

alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
alias char-major-81 bt878
alias usb-controller ehci-hcd
alias ieee1394-controller ohci1394
alias scsi_hostadapter ata_piix
alias spca spca5xx
alias eth0 skge

you might try lsusb and see if your machine sees the cam

Hi Pete
when I gave lsusb it turns
[root@localhost ~]# lsusb
Bus 002 Device 002: ID 0733:0780 ViewQuest Technologies, Inc.
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
So,can I consider its able to see the camera?By the way why the driver still says as "unknown"?
Did I do some thing wrong in compiling the driver spca5xx?
To have a clean installation of driver....how to remove old spca installation?
I added the line spca5xx as shown in your reply and replug the cam and tried "gaim" but no device found.
Thanks

[drpt]

how to remove old spca installation?,, cd to the folder and run "make clean",
see if the device is in /dev/video0 or video1
than start gaim with in terminal and check to see if it is looking for the video1 or 0
what is the output of lsmod?

Thanks in advance.

Hi Iron_Mike
There is no word about spca5xx(like yours) in /var/log/dmesg but
"usb 2-1: new full speed USB device using uhci_hcd and address 2"-I got this line.
Does it mean anything?
Thanks for solving my problem.
Bye

[Iron_Mike]

Just a quick question, did you install V4L rpm or by YUM??????

[drpt]

do a modprobe v4l2_common,
then a lsmod,, and see if the module shows up,
if it is there then do a modprobe spca5xx

oooop! looks not loaded here.Anyother suggestion?
Thanks in advance.

[svenkatesan]

Hi Iron_mike
I read some where is loaded by default when we install the system.
I didn't install v4l separately.Today I tried with yum drew blank-package not found.
When search in "rpm seek"-only v4l-conf is available,I installed that today but the camera didn't shown up.
Any other way?
Thanks

[Iron_Mike]

You're right, I went back and checked. BTW your lsmod doesn't look like the SPCA5xxx module loaded...
