    Question iSight incorporated camera

    Hi everyone,

    I can't use my webcam that is incorporated in my iMac, and I couldn't find a good solution on www.
    Can anyone help me with this ?

    Thanks,
    Lovin

    Honestly. I think it'll be a miracle if you ever get that working in anything but apple's OS

    I found this, here: LXR / The Linux Cross Reference

    _maybe_ there are some clues in here that might be useful with
    openSUSE and this kernel (which may be different from any successes in
    this search, if any):
    http://tinyurl.com/6csxxdh

    if nothing there is real helpful the OP might find it interesting or
    useful to send a nice letter to the Apple folks and ask them for the
    URL to download the Linux driver needed . . . or, alternatively they
    could supply the APIs needed for a Linux programmer who could build
    the driver for them (and would probably do it for little or no money,
    if it were released free and open source)..

    It's done
    I found an old post here, and I followed the instruction, and now it's working flawless.
    Here is the old post, for anyone who's interested: isight firmware tools how to use??????

    Cheers !
