Oh, OK. So one part of the problem is that pixma debug messages aren't showing up.
Can the tester verify as a separate task if scanning is working with twain-sane version of libusb though? It seems it may be working now? On debug output part, I see pixma is using some custom stuff to disable when NDEBUG is present. Seems pretty easy that externally included header defines NDEBUG that pixma is including but not sanei_debug.h. A quick test of that theory is to modify the file backends/pixma_common.h around line 57 and change "#ifdef NDEBUG" to "#ifdef NDEBUGBLAAAA". Also, similar change needed at backends/pixma.c line 70.
