[sane-devel] Imageclass d530

[Rolf Bensch]

Hi Nate,

I found 2 possible problems:
(1) It seems that the timeout isn't working. There's a patch for
pixma_common.c.
(2) The Windows driver sends a status request between send scan
parameters and request image block. There's a patch for pixma_imageclass.c.

Please try the patches one by one in the order shown above. If this
doesn't help, please create pixma.log again and an additional log file
with wireshark at the same time.

Cheers,
Rolf
