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 \

2. fetch gspca updates:

cd linux
git remote add gspca \
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
... 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

Hope that helps,
