[sane-devel] Canon pixma MP160

[Marcus Käll]

Hi!

I have a Canon pixma MP160 which is not supported by sane. MP150 and
MP170 are supported.

I have no idea how the MP160 interface works, but I guess it is quite
similar to MP150 and MP170, so I modified the driver for MP150 and MP170
from SANE-backends-1.0.18.

So, I added the line:
  DEVICE ("Canon PIXMA MP160", 0x1714, 1200, 0),
to the file pixma_mp150.c. This line is almost the same as the lines for
MP150 and MP170, but I changed the name and vendor id. I found the
vendor id from sane-find-scanner utility. 

After that I compiled it for ubuntu 6.06. The default SANE-backend
version for ubuntu 6.06 is 1.0.17 but the compiling process did not
complain. 
 
With those modifications xsane finds my scanner, but when I try to scan
xsane tells me that there was an error and aborts the scan.

The following lines contains the output from the pixma driver with
highest debugging enabled.

Can anyone help me with this driver?
