<pre wrap="">Hi Wade,
Well, I've done some work on the pixma backend those last months,
currently all latest work is now incorporated into the Sane CVS version,
the standalone driver (the one you are using), is not maintained
anymore, only CVS one is maintained for easiness.
The biggest difference between standalone and CVS pixma drivers is the
usb part. Standalone uses its own usb code, whereas CVS uses the
standard libusb, much more robust to my opinion.
I took a look at the information you sent:
- patch between 0.12.1 and 0.12.2
It does only concern button scan code, so this is a bit weird if it
affects normal scan. But this may be a place to dig.
- scanimage fail:
I don't have the complete log, but as far as I can see, the fail looks
to appear after the send date request, not implemented in those old
versions of the backend (pixma scanners request the date and time).
I've implemented a while back this date/time message for MP710 (which
shares the same code as MP730), so it is now present in Sane CVS code.
To dig further for MP730, my advice would be:
- Install Sane CVS
- Get a trace log as you did, zip it and send it back:
SANE_DEBUG_PIXMA=11 scanimage -d pixma:04A9262F_00000000F972 -T

<pre wrap="">Hi all
I spent some time in 2006 working with Wittawat Yamwong to get the
Canon MultiPASS MP730 (US branding) or Canon imageCLASS MP730
(Asia-Pacific branding) supported in the pixma driver. Sadly, I had to
move house at the time, the project also moved to a new mailing list
and then life got in the way and I never had time to get back onto it
until now.
The driver worked for about 90% of functionality up until pixma-0.12.1
but something broke in 0.12.2. I managed to track it down to this
diff:
--- pixma_mp730.c.orig 2006-08-27 07:37:16.000000000 +1000

const pixma_config_t pixma_mp730_devices[] = {
/* TODO: check area limits */
Applying the same patch to pixma-0.13.1 also makes it work using the
pixma test utility 'scan', but not when using the sane backend as a
library. The error message is coming out of pixma_io_sanei.c:330 which
only gets rolled into the libsane-pixma.so.1.0.19 library. I have
tried using gdb to set a breakpoint and get a backtrace but gdb makes
baby jesus cry.
Can anyone help by explaining how to debug a shared lib and/or tell me
why the pixma_write() function gets a count of 0?
Thanks,
Wade.
