those are files, not subdirs, but yes, that is what we are after.

yes, overwrite the files in 'backend', but rename rene's avision.conf
to avision.conf.in first. that is a more recent change that rene
perhaps did not make to his private copy.

then you are off to step 4. you will want to make sure you have
/usr/include/usb.h first. if not, install the libusb-dev or
libusb-devel package that came with your os.

you need to determine where your existing compilation of sane has
installed its files, and pass the correct arguments to ./configure to
use the same locations. this will overwrite the originals instead of
installing a second copy (which causes issues generally). run
configure with the --help option for more info.

basically, we want to overwrite the scanimage and sane-find-scanner
programs, (probably in /usr/bin), the saned daemon program (probably
in /usr/sbin) as well as libsane.so.* and the sane/libsane-* libraries
(probably in /usr/lib). we also want to overwrite /etc/sane.d

probably something like:

./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var

though if you are on a 64 bit linux system you might have to add
--libdir=/usr/lib64
