the current version is not ready to be included in
sane-backends yet. Many things in the source code needs to be cleaned, e.g.
naming convention for global symbols, license, coding style etc. I will look
at the code and give you an definitive answer on this weekend.

Replace and with the correct USBID of your scanner and check the
group and permission if it matches your system. See udev man page
and /usr/src/linux/Documentation/usb/hotplug.txt for more info.

is not directly related to SANE. IMHO, distributors should be responsible for
a working libusb.

before I read the SANE standard and there is also a cancel() function in my
driver but with different semantic. Now that you pointed me to an
implementation of a reader process, everthing becomes clear.
Thank you! :-)

st we
should stick with the above udev rules. For those who has an older libusb
(like me), exporting USB_DEVFS_PATH=/dev/bus/usb as a system wide environment
variable could help.

Thank you for having a look at the code. Please wait a little bit. I'm fixing
sane_get_devices() and sane_open(). They aren't compatible with the SANE
standard yet. I think, everything will be ready for SANE CVS on this weekend.

I have just uploaded the patch for SANE CVS dated 20060523.
http://home.arcor.de/wittawat/pixma/sane-pixma-0.11.1.patch.gz
May I commit changes into CVS? There could be a small status update for MP800
and MP830 in the next weeks. My account at alioth.debian.org is

_halt().
I did a grep and it seems that only avision backend currently uses
sanei_usb_read_int(). Will the backend still work if I modify the function so
that it calls usb_clear_halt() if and only if a halt condition really
occurred? (usb_interrupt_read() returns -EPIPE)

ur
project tree looks clear, you can add only your source files to the project
or set file filters accordingly. Don't forget to read
doc/backend-writing.txt. :-) I personally do a bit different. I compile my
backend outside the sane-backend tree.

ell.
$ export SANE_DEBUG_DLL=3

The debug messages will tell you whether your backend was loaded by the
libsane-dll.so. Possibly that you didn't export the API functions as
sane_khf_init, sane_khf_exit etc.

ld try to modify
the pixma backend so that you need to add only protocol specific codes and
don't need to worry about SANE API for the present.

You can start with the sane-backends CVS version (after 2006-08-
sane-net and
sane-dll for more info about configuring the backend. BTW, the protocol itself
is described in detail in Chapter 5 of the SANE Standard.

he new PIXMA MPs seem to talk a different "dialect". USB sniffer logs for
color, grayscale and BW mode are required. Please do _not_ send sniffer log
files to the mailing list because they will be probably very large! Instead,
put them somewhere in the Internet and post the links here
ile 'configure'. There is only one occurrence.)

o respond at all, does it?
The scanner did actually respond. You can see it below the "IN" lines. Did you
hear the scanner's optical unit move? Does the pixma backend work if you
directly connect the device to your desktop or laptop computer? (I'm not
familiar with the distro running on Baffalo Linkstation.)

form "_zz" where , and zz are the vendor ID, the
