[sane-devel] Ubuntu 10.4 32 & 64 bit Platform - Canon MF6550 Scanner - sane via any frontend "Hangs" at 1st data transfer

[Nicolas Martin]

Goods news then, thanks Ron for your report ;-)

Looks like your attachment (I suppose the scan log) has been suppressed
from this email (maybe size is too big), so could you retry to get a
smaller one by running these commands: 

$ export SANE_DEBUG_PIXMA=11

$ scanimage -x 100 -y 100 1> /dev/null 2> scanimage.log

Zip or tar.gz the scanimage.log file you get, and send it me back.
I would like to keep it as reference, for easier pixma backend
maintenance.
In the meantime, I'll update the docs for this model.

Concerning Ubuntu 10.04: I don't know if they'll stay with the current
sane lib 1.0.20, or upgrade it. But generally, Ubuntu ships with latest
stable Sane lib (1.0.20 at time 10.04 was released, now 1.0.21)
So I'm afraid you'll probably need to live for a while with the Sane git
version until a Sane 1.0.22 version is released, and then get ships with
Ubuntu.
However, the pixma backend is now very mature, and I'm rather prudent
when adding changes, to keep stability and backwards compatibility. 
You can either install Sane git over Ubuntu's Sane (be careful to keep
the same directories when building the ./configure statement)
Or you could also create your own Sane package with checkinstall, and
install it with dpkg so that it gets included in package management.

NB: export statements are attached to your terminal session, and get
killed when you logout or close terminal.

Nicolas
