[sane-devel] MP730 driver broken since pixma-0.12.2

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
