webcam not found since intrepid installation

[rudeboyskunk]

So I checked out the other threads on this topic, and it seems that for people in my particular situation there is no solution (or is there...?).

In Ubuntu Hardy, my generic webcam worked fine (I don't even know what type it is). I plugged it in, and camera-monitor showed it to be working right away, it worked fine in cheese and skype and everything else, no problem, right out of the box, you get the idea.

Then I did a clean install of Intrepid.

No program will detect it. Any program that would actually explain something just says "no device connected to /dev/video0" or something along those lines.

I tried my fiancee's webcam, a Logitech Quickcam, and it works great, but the quality is terrible (my webcam's quality is way better, despite being some generic thing with no name).

I've installed just about every package that all of the "linux webcam howto" manuals list, and nothing works.

Any ideas?

I have the same issue!

I only used it in skype so nothing complicated but still.

It work out of the box and now it does not.

It looks like it actually has driver loaded but still it can not be detected by skype.

this 8.10 is buggies realise every so far my webcam, microphone and graphic card stopped working properly this is dreadful.

I wish I could downgrade next time I will think twice before any "upgrade"

I too have issues with my webcams with Ubuntu 8.10. I have a built in webcam in my laptop and a USB Logitech Quickcam in my desktop. Ubuntu 8.04 detected them correctly and gave the right name under the webcam list. Skype, AMSN etc worked perfectly and the quality was good. After I did a clean install of Ubuntu 8.10 in my laptop and an upgrade in my desktop, Ubuntu 8.10 shows both webcams as USB webcam, without the webcam name. AMSN doesn't recognizes the webcam. Skype works fine with the webcam, but the video is quite dark. I need to switch 4-5 lights on to get a decent brightness. I couldn't find a way to adjust the brightness. I'm not sure what went wrong with Ubuntu 8.10 and why it went backwards as far as webcam is concerned.

I've got 0ac8:303b Z-Star Microelectronics Corp. ZC0303 WebCam. It worked from the box on 8.04. but failed after upgrade to 8.10. I've found a solution here

Thanks to Janimo, saved me from downgrade.

I did these steps (all as root!):
1) Install moreutils package. It's in the repos
2) Add the line

blacklist zc0301

in the /etc/modprobe.d/blacklist file
3) Add the line

gspca_zc3xx

in the end of the /etc/modules file.
4) Run

xxd /lib/modules/2.6.27-10-generic/kernel/drivers/media/video/gspca/gspca_zc3xx.ko |sed '/^000a370:/ s/1b30/3b30/' |xxd -r | sponge /lib/modules/2.6.27-10-generic/kernel/drivers/media/video/gspca/gspca_zc3xx.ko

If your kernel isn't 2.6.27-10 change it according to your kernel version.
5) Reboot.

The 4th step must be done after every kernel upgrade. Don't forget to change the kernel version in the code.

Both cheese and skype work flawlessly again!
Hope it'll help you too

Here's a solution to the brightness problem:

I can't get this code to work. I'm using the correct kernel version (I think) but it gives me the following error:

xxd: /lib/modules/2.6.24-21-generic/kernel/drivers/media/video/gspca/gspca_zc3xx.ko: No such file or directory
error opening output file: No such file or directory

Please check out your kernel version first:

uname -r

And then make sure you change it in both places in the code: in the beginning and in the 'sponge' command.
As far as I remember 2.6.24 kernel was in Hardy. My webcam worked fine on Hardy without any problem. Intrepid started with 2.6.27-7 and the latest one is 2.6.27-10.
And you need to get root privileges to run the code. You can use sudo or just open root-terminal:

gksu /usr/bin/x-terminal-emulator

and run the code there.
Good luck!
