Here is a suggestion. Since twain-sane binary seems to work better for you, perhaps it has a patched version of libusb that works around some OSX bug. Try comping and installing its version of libusb such that your git sane-backends links to it:<br>
<br><a href="http://www.ellert.se/PKGS/libusb-2009-09-10/src/libusb-2009-09-10-svn-macosx.tar.gz">http://www.ellert.se/PKGS/libusb-2009-09-10/src/libusb-2009-09-10-svn-macosx.tar.gz</a><br><br>If you compile and install with --prefix=/usr/local then be sure and add LDFLAGS=-L/usr/local/lib CPPFLAGS=-I/usr/local/include to your sane configure command line.<br>
<br>After that, if its still failing then turn on USB debug options.<br><br>export LIBUSB_DEBUG 255<br>export SANE_DEBUG_SANEI_USB 255<br><br>Chris<br><br><div class="gmail_quote">On Fri, Jun 18, 2010 at 8:14 AM, <span dir="ltr"><<a href="mailto:twain43@hotmail.com">twain43@hotmail.com</a>></span> wrote:<br>

I'm a bit lost too....<br>If you find somethign else we have not yet tried, just let me know, and I'll see what I can do: for the moment, the only thing I can think of is trying to clean every bit of SANE on my sys and try recompiling and installing with the latest development snapshots....but I guess they're of no use, if the Pixma module has not changed....<br>
