[sane-devel] help for write back-end

[corwin]

Hi,

I have a CanoScan 3200F (Product Id : 2216) and this scanner are not 
supported by sane.
But i'm very interresting for write a back end.

I use "usb snoopy log" for extract usb log under WinXP. And I had 
writing a perl script (based on awk Thomas Soumarmon's script) for 
genrate c code for replaying log-script under linux (debian, 2.6.9).
For the moment I reading libusb documentation and my first objective is 
to write a small program (sane independant) for activate the scanner.

But actually i'm completly lost into the log data and i don't know how 
to begin !!!

So my questions :

Have you a methodology for extract information of data log ?
Where can I found script (perl, ..) for parsing and cleaning log data ?
Have you trics ?

ps: I don't know the model of chips into the scanner and i don't open 
this because it is one plastic box and there are no visible screw...
pps : I'm very sorry for my poor english :(
