Angry Logitech QuickCam Chat on FC5 (spca5xx not work?)

Hello to all!

I'm new in Fedora Core world (long time used Slackware). I have Logitec QuickCam Chat (046d:092c) web camera that works on kernel 2.4.32 in Slackware. FC5 is updated to kernel 2.6.17-1.2174_FC5 and I downloaded latest spca5xx source package from http://mxhaard.free.fr/download.html . There is my problem:

Code:
[root@urosevic spca5xx-20060501]# make clean
rm -r -f drivers/usb/*.o drivers/usb/.spcadecoder.o.cmd \
drivers/usb/.spca5xx.o.cmd  *.o *.ko *.mod.* .[a-z]* core *.i
[root@urosevic spca5xx-20060501]# uname -a

FATAL: Error inserting spca5xx (/lib/modules/2.6.17-1.2174_FC5/kernel/drivers/usb/media/spca5xx.ko): Invalid module format
What's wrong there? How to load spca5xx, or I need gspca-v1 (where to get them, DAMN!)?

TIA

Hi all, I've installed this new module, gspca, It worked.

BUT, after a reboot it stoped working!!! I guess it's a conflict between FC5 own driver
and gspca.

I need help.

Just do
Code:
# modprobe gspca
and they should work again. Add gspca module to modules.conf or to rc.local script

Thank you Urke.

When I do "modprobe gspca" it returns the following message:

FATAL: Error inserting gspca (/lib/modules/2.6.17-1.2187_FC5/kernel/drivers/usb/media/gspca.ko): Unkn own symbol in module, or unknown parameter (see dmesg)

and dmesg has:
gspca: Unknown parameter `index'

do you know why?

thank you.

Hi Urke.

To solve, I was told to remove the references to gspca from /etc/modprobe.conf.
and redo modprobe gspca.

and it WORKED!!!

Here are the notes I used to get gspca working with Logitech QuickCam for Skype:

- download source package from:
http://mxhaard.free.fr/download.html

wget http://mxhaard.free.fr/spca50x/Downl...0060925.tar.gz

- extract
tar xfz gspcav1-20060925.tar.gz

- install kernel metadata:

yum install kernel-devel

- install kernel sources:

http://download.fedora.redhat.com/pu...dates/5/SRPMS/

wget http://download.fedora.redhat.com/pu...ates/5/SRPMS/k
ernel-2.6.17-1.2187_FC5.src.rpm
rpm -i kernel-2.6.17-1.2187_FC5.src.rpm

- compile/install kernel module:

cd gspcav1-20060925
make
make install

- load it:

/sbin/modprobe gspca

- check it:

/sbin/lsmod | grep gspca
ls -ald /dev/video*

NOTE: no entry needs to be added to /etc/modprobe.conf,
gspca module will load automatically after reboot

- launch ekiga and turn on video and see the image
- if you do not have ekiga, just install it via 'yum install ekiga'

Thank you for this info vladak. I have been able to get my Creative webcam working with your helpful guide.

However, I did have one problem. It seems that on my system uname -a reports version 2.6.15-1.2054_FC5 of the kernel, but it is actually revised up to version 2.6.16. This meant that I saw "unknown field owner specified in initializer" errors during compilation.

Based on info found elsewhere on the interweb I found that I was able to comment out all references to .owner in the gspca_core.c file before running ./gspca_build as apparently it's not needed.
