Bruce, this is what is related to v4l:

Built with
sed -i 's/SYSFS/ATTRS/g' tools/sane-desc.c && # You say we won't need
./configure \
--prefix=/usr \
--sysconfdir=/etc &&
make &&
make install &&
install -v -m644 tools/udev/libsane.rules \
/etc/udev/rules.d/65-scanner.rules
$ ls -lh /etc/udev/rules.d/65-scanner.rules
-rw-r--r-- 1 root root 104K Abr 29 13:44 /etc/udev/rules.d/65-scanner.rules
Don't know if this is relevant:
$ paco -dd xf86-video-v4l
13-Apr-2012 02:19 xf86-video-v4l-0.2.0
I have not used this patch, as I do not have libv4l:
https://projects.archlinux.org/svntogit/packages.git/plain/trunk/libv4l-0.8.3.patch?h=packages/sane
Inside that, can read:
