Sebastien: for reference, here's a way to build a kernel with
CONFIG_USB_DEBUG enabled.
# prerequisites
apt-get install git build-essential
# get the kernel history, if you don't already ahve it
git clone \
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
# configure
cd linux
cp /boot/config-$(uname -r) .config; # current configuration
scripts/config --disable DEBUG_INFO
make localmodconfig; # optional: minimize configuration
scripts/config --enable USB_DEBUG
# build, test
make deb-pkg; # can use -j<num> for parallel build
dpkg -i ../<name of package>; # as root
reboot
Thanks,
Jonathan
