Hi,

At the moment there is no specific support for the new devices, so you
are most welcome to help. As there already exists code that might be
able to support these devices without any (or not much) development
please try the following, using the CVS sane-backends code.

You can try adding the definitions near the end of pixma_mp150.c where
similar definitions exist, like this:

  /* Latest devices (2010) Generation 4 CIS/CCD */
  DEVICE ("Canon PIXMA MP280",  "MP280",  MP280_PID,  1200, 638, 877,
PIXMA_CAP_CIS),
  DEVICE ("Canon PIXMA MG5100", "MG5100", MG5100_PID, 1200, 638, 877,
PIXMA_CAP_CIS),
  DEVICE ("Canon PIXMA MG6100", "MG6100", MG6100_PID, 2400, 638, 877,
PIXMA_CAP_CIS),
  DEVICE ("Canon PIXMA MG6200", "MG6200", MG6200_PID, 2400, 638, 877,
PIXMA_CAP_CIS),
  DEVICE ("Canon PIXMA MG8100", "MG8100", MG8100_PID, 4800, 638, 877,
PIXMA_CAP_CCD | PIXMA_CAP_TPU),

and the USB ids near the start of the file under the existing ones, like this:

#define MP280_PID 0x1746
#define MG5100_PID 0x1748
#define MG5200_PID 0x1749
#define MG6100_PID 0x174a
#define MG8100_PID 0x174b

Compile and then see if the device can work at all. Note the MG
devices are sold under different names in different parts of the
world, so the last 2 digits above are simply 00 to denote the family.

(other new device USB ids given here for reference)
Regards,
Gernot
