Took longer than usual, but I did as you recommended.
1. Built the libusb version linked and installed it;
2. Exported only PIXMA and scanimaged. Log in the attached zip file;
3. Exported LIBUSB and SANEI USB debug. Log in the attached zip file;

No news, I'm a fraid.

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:


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

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....
