No. But  you should need gspcav1 kernel module:

http://atrpms.net/dist/fc6/gspca/

Install and load the module (or reboot).

How does one deal with this?

camE
can't load font arial/8
can't load font arial/8
can't load offline image /home/gilbertt/.block.jpg, ignoring

^^^ this is irrelevant, simply config issues with camE

open /dev/video0: No such file or directory
^^^ this would imply that either your camera isn't supported by
the kernel module or the module isn't loaded...or for some
bizarre reason it's on video1 or something.
Can you verify that the kernel module is loaded?
Should it show when I do lsmod?

That produces a long list but nothing I recognize as related to this.
Should do.
Open a terminal and do:
su -
tail -f /var/log/messages

Then in another terminal do:
modprobe gspca

and see what happens in the first one...it should detect your webcam and create /dev/video0 - if it still doesn't, paste the output to us here?
modprobe gspca
FATAL: Error inserting gspca (/lib/modules/2.6.20-1.2948.fc6/updates/drivers/usb/media/gspca.ko): Invalid module format
and in messages ;

May 23 09:16:32 box6 kernel: Linux video capture interface: v2.00

This would imply that you're trying to load the wrong kernel module
for that kernel.
You appear to be running an i586 kernel, which could possibly mean
that you've got bitten by the anaconda i586 kernel install bug.
You can get a script to fix this:
download it and execute it as root from

http://fedoraproject.org/wiki/Bugs/FC6Common?action=AttachFile&do=get&target=kernel-fix.sh
To do this, in your root shell do:

wget http://fedoraproject.org/wiki/Bugs/FC6Common?action=AttachFile&do=get&target=kernel-fix.sh
Nor will it work for me:   10:04:58 ERROR 403: Forbidden.

(this was failing for me with 403 forbidden, but might work for you)

Then do chmod 770 kernel-fix.sh
then do ./kernel-fix.sh

Ok, I ran the first URL from Firefox and it appeared to work with a few cryptic [to me] error messages that I lost when it asked me to reboot the computer.
Now I have:  uname -a
Linux box6 2.6.20-1.2948.fc6 #1 SMP Fri Apr 27 18:53:15 EDT 2007 i686 i686 i386 GNU/Linux
Is that the correct Kernel?

modprobe gspca
FATAL: Error inserting gspca (/lib/modules/2.6.20-1.2948.fc6/updates/drivers/usb/media/gspca.ko): Invalid module format
And the following in messages after doing modprobe gspca:

May 23 10:29:06 box6 kernel: Linux video capture interface: v2.00
May 23 10:29:06 box6 kernel: gspca: no version for "struct_module" found: kernel tainted. May 23 10:29:06 box6 kernel: gspca: version magic '2.6.20-1.2948.fc6 SMP mod_unload 686 4KSTACKS ' should be '2.6.20-1.2948.fc6 SMP mod_unload 586 4KSTACKS '
Looks like it's not the right kernel.

My mistake above, not awake, sorry.

do
wget wget http://fedoraproject.org/wiki/Bugs/FC6Common?action=AttachFile\&do=get\&target=kernel-fix.sh
(so you're adding \s in front of the &s so it'll work on the command
line)
and then as root do:
chmod 770 kernel-fix.sh
./kernel-fix.sh

and paste the output somewhere and save it so if it doesn't work you can get it back

Ok, I did:
wget http://fedoraproject.org/wiki/Bugs/FC6Common?action=AttachFile\&do=get\&target=kernel-fix.sh
Install/reboot/etc.

and   modprobe gspca

and then I see the following in lsmod:

lsmod

Module                  Size  Used by
gspca                 643792  0
videodev               29633  1 gspca
v4l2_common            26945  1 videodev
v4l1_compat            16581  1 videodev
radeon                116065  2
drm                    78421  3 radeon
-----------   snip   -------------------

I still don't see a /dev/video but this appears to be a step forward anyway.
Thanks.

Bob Goodwin
