Getting Ali Webcam working under Intrepid

    I'm not by any stretch a Linux expert, although I've been running it for a
    couple of years on my last two laptops. I currently have an Asus Z92 style
    laptop, running an AMD Turion 64, which may be relevant.

    I have been trying to set up my in-built webcam, but unfortunately am finding
    the instructions a little hard to apply in my case.

    Running "lsusb" includes the following line:
    Bus 004 Device 004: ID 0402:5603 ALi Corp. USB 2.0 Q-tec Webcam 300

    Running "uname -a":
    Linux Pippin 2.6.27-11-generic #1 SMP Wed Apr 1 20:53:41 UTC 2009 x86_64 GNU/

    I downloaded the 2.6.27 version:
    "Intrepid or Kernel >= 2.6.27
    The latest driver only works with kernel version >= 2.6.27 (Intrepid) is here:"

    I compiled it, and apart from 5 or 6 warnings it seems to have completed ok. I
    then ran "sudo make install" and that seemed to go ok too. "sudo modprobe
    gspca_m5602" returned no output so I assume that was ok, although I'd like to
    be certain this is the one for my 5603 webcam?

    Looking in Package Manager, I have libv4l-0 (0.5.7-1) installed (after this
    didn't work, I was looking at some other help sites and installed lib32v4l-0
    (0.5.7-1) as well - no difference).

    Problem is Ekiga and Skype still say "No video device".

    I tried "export LD_PRELOAD=/usr/lib/libv4l/" and running "skype"
    after that from the terminal and get the message
    "ERROR: object '/usr/lib/libv4l/' from LD_PRELOAD cannot be
    preloaded: ignored."

    This was the stage I installed lib32v4l-0, and tried
    "export LD_PRELOAD=/usr/lib32/libv4l/" instead.
    Running "skype" after this doesn't give the error.

    Conversely, running "ekiga" works for the first setting and not for the second,
    from which I surmise that I am running 32-bit Skype and 64-bit Ekiga?

    On Ekiga I can choose V4L or V4L2 - no difference.

    Have I missed something, or is this a hardware difference? I have had the
    webcam working under Windows.

    Many thanks,

      So did it finally work with either skype or ekiga or not? I didn't quite understant.

      Sorry, that "works" was a red herring - I just meant that I did or didn't get the ERROR.

      In summary - I have had NO joy in my webcam detecting under ANY software, apart from at the USB level.

      Do you have any tips?
