<br>
Firstly, please send the output of ``lsusb -v'' for the Canon device so
that we can confirm that it also suffers from the bug in
sanei/sanei_usb.c where it tries to use the wrong endpoints. See
<a class="moz-txt-link-freetext" href="http://waddles.org/content/sane-canon-mp730-driver">http://waddles.org/content/sane-canon-mp730-driver</a> for more info. There
is still some work to be done for reliable support but the patches
there should at least get it working.<br>
<br>
AFAIK, SmartBase, imageCLASS and MultiPASS are all just different
marketing names for the same devices, depending on which region they
were sold in.<br>
<br>
Regards,<br>
Wade.<br>

<pre wrap="">Hello,
I know this issue has been discussed extensively during the past month.
I'm trying to get working a Canon SmartBase MP700 Photo (this is a
European model); lsusb reports:
ID 04a9:2630 Canon, Inc. MultiPASS MP700
with easily predictable scanning results:
Error during device I/O
I have also been reading the threads "MP730 driver broken since
pixma-0.12.2" and "ERROR DURING READ: Error during device I/O PIXMA" and
realise there has been success and that work is planned on this soon.
The attached log was obtained using the instructions quoted below;
they're from the thread "ERROR DURING READ: Error during device I/O
PIXMA".
I understand my device is not the same as the PIXMA, but the error seems
to be the same and I'm thinking maybe I am able to provide useful info.
The system is Ubuntu 9.04, kernel 2.6.28, libusb 0.1.12, sane-backends
compiled from latest (20090509) git snapshot.
Hope this is useful. Looking forward to using the device in Linux :-)
Thanks,
Dominik

Yes, I took a look at it, and it looks like a timeout in libusb
interrupt read is not correctly taken into account.
Could you get a more detailed thread like this:
$ export SANE_DEBUG_SANEI_USB=255
$ export SANE_DEBUG=255
$ export SANE_DEBUG_PIXMA=21
$ scanimage -T &> scan.log
