Instructions for Hugo:

	# prerequisites
	apt-get install git build-essential

	# 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

	# latest mainline kernel
	cd linux
	git fetch origin
	git checkout origin/master

	# configure
	cp /boot/config-$(uname -r) .config; # current configuration
	scripts/config --disable DEBUG_INFO; # smaller build
	make localmodconfig; # minimize configuration

	# apply patch
	git apply --index /path/to/patch

	# build
	make deb-pkg; # optionally with -j<num> for parallel build

	# test
	dpkg -i ../<name of package>; # as root
	reboot

	# to unapply patch:
	cd linux
	git reset --hard origin/master

	# when you want to build again:
	make deb-pkg; # maybe with -j4
	dpkg -i ../<name of package>; # as root
	reboot

I would also be interested in a capture of the pairing event, if possible:

	(remove mouse battery or bring mouse out of range)
	mount -t debugfs debugfs /sys/kernel/debug
	ls /sys/kernel/debug/hid/
	modprobe -r hid_logitech_dj
	modprobe hid_logitech_dj
	cat /sys/kernel/debug/hid/<device name>/events >events.captured
	(insert mouse battery or bring mouse within range)
	^C
