[sane-devel] Canon PIXMA MX890

[Henry Ptasinski]

Rolf,

I don't have an XP machine up and running at the moment.  I may have one 
in a while, but not sure when.

I believe the problem occurs via both USB and network, so could this be 
debugged by sniffing network traffic instead (and preferably using a 
different OS than XP).
