That should allow you to build sane-backends with USB support. The
backends should be using libusb-1.0 if I understood the libusb formula
Yurii pointed out.

That's libusb-1.0, all right.

It should be unrelated. I'm assuming that the [sanei_usb] log messages
above were produced by running »scanimage -L«. Have you tried running
this with root privileges? That is, something like
sudo SANE_DEBUG_SANEI_USB=127 scanimage -L
It could be a permissions issue, in which case the above should work
around that. Another thing you may want to try is replugging the USB
cable (or power-cycle the device) *after* you install 1.0.27 and wait
for a bit, say half a minute to be on the safe side, to let the "dust
# I know next to nothing about the Mac's (BSD's?) USB support and device
# hotplug handling but normally when you replug or power-cycle, the
# kernel notices and issues a number of events that the OS can react to.
# One of the things the OS could do is change device access permissions.
# These things may take a little time to be dealt with.
On the other hand, it may also be that your device is still getting its
act together. In that case, you should wait and try again after a
suitable amount of time (30s? 1m?) Or that the software that wants to
use it, scanimage, should somehow set the USB configuration first, in
which case the code probably needs to be changed.
Another thing to check is whether the genesys.conf file is installed
*and* found by the backend (and that your backend is actually enabled).
For that, something like
SANE_DEBUG_DLL=127 SANE_DEBUG_GENESYS=127 scanimage -L
should provide some insight.
# Combining with the earlier sudo command, you could run
# sudo SANE_DEBUG_SANEI_USB=127 SANE_DEBUG_DLL=127 \
# SANE_DEBUG_GENESYS=127 scanimage -L
# and paste the debug log somewhere where we can all admire it ;-)

Which is supported by the genesys backend, but isn't this the output of
sane-find-scanner and not »scanimage -L«? Both programs report *very*
different things. The former just says whether your device might be a
scanner, irrespective of any SANE support; the latter says whether your
device is usable by SANE under your current configuration settings.

That only shows the build bits. Those are fine now. You have a
run-time issue now.
Hope this helps,
