[sane-devel] Canon PIXMA MG6350

[Theo]

Hi again Rolf,

I cannot reproduce the error right now; scanning works fine both via 
both USB and network. I'm testing with scanimage going forward :-)
Whenever the problem re-occurs, I'll try to gather the debug info per 
your instructions.

I'll also look into the scanner daemon; this is the debug output when I 
use the button Scan --> Black

...
   Buttons:
     --button-update
         Update button state
[pixma] INTR T=1.045 len=32
[pixma]  00000000:00 00 00 00 01 01 03 02  01 00 00 00 00 00 00 00
[pixma]  00000010:00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00
[pixma]
     --button-1 <int> [0] [read-only]
         Button 1
...

With Scan --> Color byte 7 changes from '02' to '01'

I hope this is helpful.
