[sane-devel] Canon Pixma MX435 Detection

[Louis Lagendijk]

hello Nick,
It would indeed be interesting to see if USB works but I suspect the
network code. As soon as I have some time I will test over Wlan. I
suspect a timing issue. 
In the recent rewrite when I added scan button and IPv6 support I may
have broken something. My device is normally ethernet connected.
My time is right now limited (too much work at $DAYJOB), so it may take
a week before I will be able to do so.

kind regards, Louis
