[sane-devel] Canon Canoscan 4400F

[martin]

Hello all.

I decided to try add my scanner to sane. I'v read the recommendations 
about how to do it however they are really rather general.

I have Canon Canoscan 4400F. In the table with supported scanners is at 
this type written to be added to genesys backend. I just downloaded the 
sources and there some places with defined values for each scanner. So 
far okay.

Then i followed the advices and made some logs about usb traffic in the 
windows environment (Snoopy2). There some common parts.. there is always 
some bunch of data sending to the device at startup (possibly firmware) 
.. there is still some traffic up and down.. some checking and so on... 
however is there any advice how to recognize more? O just described 
somewhere some process how to test  sending bunches of data to the 
device via usb? Or should i use another sniffing tool to get better 
readable usb logs?

Thanks for advices.
