Logitech QuickCam pro 4000 -- Debian

Hi,

I'm curently trying to run a logitech web cam (QuickCam Pro 4000). It is using a philips chipset and is suported by the pwc drivers. I am running a 2.4.18 kernel on a debian system (debain pre-compiled kernel).

I can insert the pwc module, here is what i get in /var/log/message:

It does not state it has seen the webcam and does not create the /dev/video0. I tryed to create video0 myself (mknod /dev/video0 c 81 0) but there does not seem to be a difference.

The /proc/modules says:

Quote:

uhci 23720 0 (unused)
usbcore 48512 0 [pwc uhci]

ext3 56736 1 (autoclean)
jbd 35048 1 (autoclean) [ext3]
unix 13316 5 (autoclean)

Both uhci and pwc are marked as unused??

Bottom line is my video app says: cannot open /dev/video0. I believe it is because the drivers are not loaded corectly. (by the way, I know there are not the latest drivers, but I want to avoid recompiling a kernel)

Any ideas? Thanks in advance.

I just answer my own question:

Quote:

Some cameras such as the Logitech QuickCam 4000 Pro require a PWC version later than PWC 8.6 and a kernel version later than kernel version 2.4.18

I upgraded the kernel with kernel-image-2.4.27-2-tsc-586 package. It all seems to work fine.

Hope this can help some one else.

hi,
Iam using Fedora Core 3 and the kernekversion is 2.6.9 and i tried to install a pwc-10.0.6a drivers for my logitech QuickCam Pro. It does not create the /dev/video0 device as soon as i connect the camera to my pc. What shall I do??This is very important to me as I have to do my project on linux using my web cam. Can u plzzz help me in configuring my web cam ??

I think it's impossible, fedora does not use devfsd, so.. by default /dev/video0 is already exist.
also check videodev and pwc kernel module are already loaded.
