That looks good.

Please try the attached patch. This should enable button support for
your scanner.

Save the attached file to the folder '[sane source/]backend' and patch
pixma_mp150.c with 'patch pixma_mp150.c pixma_mp150.c.diff1'.

Now you can test with 'scanimage -d pixma:MX890_192.168.2.102 -A'.
Button-1 is your color button and button-2 is your black button.
Original contains the image size (01=A4; 02=Letter; 08=10x15; 09=13x18;
0b=auto) and target contains the scan format (01=JPEG; 02=TIFF; 03=PDF;
04=Kompakt-PDF). If your scanner shows other or more parameters, please
report them.

Cheers,
Rolf
