hello Per,
Nicolas Martin was the one that implemented the MP970 support that is
now available in CVS. I worked with him by providing some USB traces. We
finished the platen scanning.
We started on film strip scanning but had some problems finding out what
is required and where it differs from normal scanning. 

I have since been working on supporting the proprietary network printing
for the MP970 with cups (available from sourceforge) and have not been
able to get back to him with more information. I have now started work
on network scanning support in Sane. That will keep me busy for some

Nicolas is a very nice gentlemen to work with. I have not seen him on
the list lately. I assume that he is on a holiday or business trip and
will react to you when he gets back to the list. I am sending him a copy
(bcc) of this reply to make sure he gets back to you

anyhow, the issue is not so much the USB code, but the actual sequence
of commands to turn on the backlight and perform the scanning. If you
are interested, make some USB traces under windows (snoopy pro is the
name of the windows tool if I remember correctly) and have a look at the
code in pixma_mp150.c to see what needs to be added

kind regards, Louis
