Thread: How do I compile and install qc-usb?

  1. #1

    Default How do I compile and install qc-usb?

    I want my Logitech QuickCam Web to work on SUSE11.1.
    I know about the qc-usb driver from sourceforge.net.

    What I know I don't know is:
    a) How to get hold of the SUSE11.1 kernel source code and where it gets placed in the filesystem
    b) How to configure it (?) so that (I presume) the source matches the object code.
    c) Which compiler apps I need and what they are called and can I get them via Yast?
    d) As I have installed via CD I am missing lots of stuff that I would have if I had installed by DVD. How can I download all the stuff I am missing?

    Thanks

    Hi Zaitor,
    Yes...I think that's what I want.
    I'm not sure how to interpret your post. How do I get hold of the driver...is it in 11.2?

    Just fire up yast2 softwareinstaller and search for it, should be in the
    oss repo

    Yes, I found it and it is already installed. The note says that this driver is "Derived from qce-ga, linux V4L driver for the QuickCam Express and Dexxa QuickCam"

    Mine is a Logitech QuickCam Web, ID 0850.

    Certainly nothing happens when I plug the camera in and "cheese" doesn't recognize it. I've installed xawtv too but when I run it it fizzles out and does nothing at all.

    The sourceforge site claims that their qc-usb driver works with my camera. The problem I am having is that their installation instructions simply do not work in my SUSE. I fear this may be because I loaded off a live CD and I don't have all the necessary files such as kernel source files.

    Has anyone out there managed to install this driver in SUSE 11.1?

    Having looked again at the sourceforge site, it would surprise me if the driver I already have doesn't work. They specifically say that the qc-sub/gce-ga supports my camera and the other two that are mentioned by Yast.

    Before I let things get out of hand, is there a way I could check whether the driver I have is actually working with my camera, even though "cheese" doesn't?

    What is the best application to test the camera with, if not cheese?

    Thx

    make sure you have libv4l installed, and try ekiga.

    I never got my qc-usb cam to work with cheese ( in reality gstreamer) until now on 11.2, and even now only after a hack explained in lib4l readme.
    (only applies for 11.2)

    For me the cam worked in ekiga + websites with flash cam support

    Note : the quickcam-kmp-default driver is not needed anymore for 11.2 since the cam is now supported by the kernel why its still packaged I do not know

    Something may be happening. I uninstalled the quickcam driver. Then rebooted, and reinstalled it. I installed libv4l. I installed ekiga. When I ran ekiga the green light on the camera came on for a second. Ekiga didn't show any camera image. I closed ekiga and openned Cheese, but it claimed it couldn't find a camera.

    I then unplugged the camera and plugged it back in. A pop-up appeared saying:
    detected new audio device
    PTLIB/ALSA
    use as default device?

    I chose "yes". Same behaviours after that.

    Here's part of the Yast Hardware Information dump. I guess this proves the driver is there and the camera is recognized. Now, how to get the apps to recognize it correctly?
    Close now....

    Well:

    Code:
    /lib/modules/2.6.27.29-0.1-default/updates/stv06xx/gspca_stv06xx.ko
    alias:          usb:v046Dp0850d*dc*dsc*dp*ic*isc*ip*
    :-)

    However, I have no idea if the camera will work with that (patched) driver.

    So tell us a little more about that "lib4vl-hack" you needed on 11.2
