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

something like "libusb:/dev/bus/0

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.)

put them somewhere in the Internet and post the links here

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.

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.

_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)

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

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.

Replace and with the correct USBID of your scanner and check the

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.
