Is there a USB Video Class (UVC for short) driver that will work in Mandriva 2008.0? I thought I read that the kernel was supposed to be UVC compliant, but I can't get a Logitech Quickcam Pro 9000 to work which needs this driver. This will be the second $100+ cam I've bought in the past week that I can't get to work.

Update: I Do have a CONFIG_UVC=m entry in /boot/config, and was able to see the cam in ekiga after selecting the v4l2 driver.

That is the only place I could get the cam to work at all, and the picture is so bad that if I can't get any improvement I'll just throw the camera away. And this is from a camera that is supposed to have a superior image.

I can't get it to work with camstream, camE, or anything else I've tried. These programs work fine with cameras that use the dkms-gspcav1 driver.

I also have not heard of anyone who has been able to get sound to work.

Unless anyone has some ideas, it looks like I'm starting to collect lots of expensive paperweights.

Seems like alot of these new modules do not work with apps like you mention unless you get the very latest cvs bleeding edge versions. Basically beta version.

Since you mention using the kernel version I would download the latest source of uvc from here and compile and give it a try. http://openfacts.berlios.de/index-en...itle=Linux+UVC

Guess I'll give it a shot as soon as I get brave enough. Thanks.

I have a quickcam pro 5000 which I had to compile and install the Berlios driver to get it to work on 2007.0, but on 2008 it just works. When I plug it in, aMSN, for example, just sees it and it just works. (I do realise that this is a different model, but I'm guessing it's not that different.)

Do have a go with the Berlios; the svn download seems to break every now and again, but once you have it, it's not too difficult to compile and install the driver.

If you look at /dev/video* you should see something there when it's plugged in.

I have got one pro 9000 on saturday and it really works fine.At the first moment I was a bit frustated from the image quality.But after compiling the latest uvc driver from svn and installing luvcview I'm more satisfied. But keep in mind that the driver is in a early stage of developmnet. The cam is definitly not a paperweight. I started a videocall with the latest
beta-skype (2.0.0.13) and it seems to be ok .

Ok thanks, I'll try compiling the latest driver. Have you found any other software that will work with it?

Another option is to try the 2.6.23 kernel from the "main" release.If you want to compile it's a good idea to backup the old driver ( 3party/uvc) and to replace the old sources IMHO. I use mainly lucview (http://mxhaard.free.fr/spca50x/Inves...0070512.tar.gz) which is unfortunately a bit buggy. With [asdf@localhost~]$ luvcview -f jpg -s 640x480 -i 25 fps a window will pop up and after a while you'll see a picture.Nearly every time I must set the AutoExposure to 1 and then set Exposure manualy very high. After correction of brightness and contrast everything is ok. The second I use is the mplayer with gmplayer tv:// -tv driver=v4l2:fps=25:width=640:height=480 it works very fine (but it must be the latest release you can get; I use the 1.0-1.rc2.3 version). If the picture is a little dark then use another driver from the preferences ( maybe GL) so you can use the equalizer.Besides skype with amsn it works excellent ( this is a very limited experience but with the best results )

Hi hfl104, I'm on a Debian Sid i386 PIII platform. I've gotten a Logitech QC 9000 Pro today after having seen that it is supported under linux (uvc driver) and should work under SkyPE 2.0 beta. Well, sadly, mine does not, although it works fine with v4l2 drivers under Ekiga, (g)mplayer and aMSN (excellent, in fact). When I ask VLC or mplayer to use the v4l application drivers I get messages to the effect that the compatibility layer is broken. Also, luvcview shows garbage with no controls, so perhaps there is an SDL issue. However, I could not find any mention of such in regard to luvcview. Will try to get it to work on another machine (different video card).

Many thanks in advance for any comments,
Gernot Hassenpflug, Tokyo, Japan.

Followup: QC 9000 Pro works perfectly on a Toshiba i386 laptop with nVidia card in SkyPE 2 Beta, and also on an AMD64 machine with 32-bit SkyPE 2 Beta installed. So problem appears to be the video on my desktop i386 machine or the nVidia card I have there, not SkyPE and not the QC 9000 Pro. Done here... thanks. G.

So, yes the webcam works under Linux, however it is somewhat picky with wich applications it wants to work. Seems v4l interface does NOT work, I only can get it to work with v4l2! The microphone does not seem to work neither, but I did not really check this. This under Mandriva 2007 (with stock 2.6.17 kernel) and Ubuntu Gutsy Gibbon.

Problem with garbage in luvcview and SkyPE with V4L on i386 solved:

In response to my problem above, I can happily announce that after a kernel upgrade today, to
2.6.22-3-686-bigmem #1 SMP Mon Nov 12 09:52:20 UTC 2007 i686 GNU/Linux,
and the installation of the uvcvideo module, all works as expected! As I noted, I had no problems on an Ubuntu AMD64 Gutsy system with GTX 7800 nVidia cards, nor on a i386 laptop with Go 6600/6200TE card (on the latter I did the kernel upgrade before testing the camera).

That's right. The uvc driver implements the V4L2 API. I've no experience with mdv 2007 - at the moment I use the 2008 version with the latest kernel
from the cooker main release; and for the microphone ..... it works without any issues in the most apps. (Only in amsn I can't choose it)
