    Actually cc-ing this time. Sorry for the noise.

    Thanks again.

    If you get a chance to test Hans's media-for_v3.5 branch, that would
    be interesting. It works like so:

    0. prerequisites:

    apt-get install git build-essential

    1. get the kernel history, if you don't already have it:

    git clone \
    git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

    2. fetch gspca updates:

    cd linux
    git remote add gspca \
    git://linuxtv.org/hgoede/gspca.git
    git fetch gspca

    3. configure, build, test:

    git checkout gspca/media-for_v3.5
    cp /boot/config-$(uname -r) .config; # current configuration
    scripts/config --disable DEBUG_INFO
    make localmodconfig; # optional: minimize configuration
    make deb-pkg; # optionally with -j<num> for parallel build
    dpkg -i ../<name of package>; # as root
    reboot
    ... test test test ...

    I ask because there have been some gspca core fixes cooking that are
    not part of the 3.4.y tree, though none of them looks especially
    relevant.

    Hope that helps,
    Jonathan
