[sane-devel] debug file attached (Re: Canon MP710/740 support request)

[Nicolas]

Hi Gernot,

That sounds great news, and we can inform the Sane list then! 

I had a look at the debug trace you sent me, and everything looks right,
working as expected. 
I'll keep it anyway as a reference, if needed.
Let us know if you are able to reproduce the problem you had before, and
if you can get such
a trace with the error, please send it, as to investigate more.
One point that could be done to improve the driver is to implement the
send_time function, as the 
scanner asks for it. Would be needed for that, a Snoop of the usb port
with the Windows driver. 
But why a scanner would need time? It seems to work fine without it
anyway.

For now, I'll update the current stand-alone Pixma driver with Pixma
MP710 and MP740, as well as
the patch to Sane files, so as to have it included in future Sane
releases too.

Thanks again for your participation and help for enhancing the Pixma
Sane driver

Regards
Nicolas
