Hi,
I have spent a while getting sane to work with my USB scanner..=20
I found that I needed to tell it to use the 1.0 API otherwise it would=20
cause a crash in libusb (not sure whos fault it is).
To do this I made a port which installs the requisite pkg_config files=20
so that the base libusb can be seen by SANE without an issue.
Here is the diff to SANE so it uses the 1.0 API..
diff -ur /usr/ports/graphics/sane-backends/Makefile=20

The libusb port is at http://www.dons.net.au/~darius/libusb_base.tgz
Note that (obviously) the SANE port needs to depend on libusb_base,=20
however I don't know the best way to do that in terms of backward=20
compatibility. ie wether libusb_base should be merged with libusb or=20
ports are modified so that they select which one.
The former seems more elegant to me but I don't know how to merge=20
them :)
