Can you take a look at the logs on
http://waddles.org/content/sane-canon-mp730-driver and tell me if you think
I'm on the right track with the endpoints?

I CBF re-installing Windows, but I did test a successful scan with
mp150-0.12.2 followed immediately by a try with pixma-0.15.0 but it failed
so I doubt it has anything to do with power-saving modes.
