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:
http://www.ellert.se/PKGS/libusb-2009-09-10/src/libusb-2009-09-10-svn-macosx.tar.gz 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. After that, if its still failing then turn on USB debug options. export LIBUSB_DEBUG 255 export SANE_DEBUG_SANEI_USB 255 Chris On Fri, Jun 18, 2010 at 8:14 AM, <twain43 at hotmail.com> wrote: > I'm a bit lost too.... > 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.... > > Twain28 > > > Subject: RE: [sane-devel] Testing on Canon MF6580PL > > From: nicolas0martin at gmail.com > > To: twain43 at hotmail.com > > CC: sane-devel at lists.alioth.debian.org > > Date: Thu, 17 Jun 2010 22:16:45 +0200 > > > > Running a bit out of ideas why it behaves like this and why logs do not > > come out from the backend. > > Probably something runs differently on MacOS, but I cannot figure out > > what exactly. > > > > Nicolas > > > > Le jeudi 17 juin 2010 ? 16:47 +0000, twain43 at hotmail.com a ?crit : > > > Already tried. > > > 100% same log (see cut-paste below). :( > > > > > > > > > > > ------------------------------ > nome.cognome @...
