<p dir="ltr">Agreed. Awesome news. I don't have a whole lot of time, and no programming experience since like freshman year, but if I can help with something let me know--sniffing or testing or whatever.</p>

Hi all,<br>
<br>
So I sort of messed up and picked up this scanner. Now I#m debating whether to return it or not. If there's hope for support in the (not so distant) future, I'll hold off and wait. I'm just touching base to see what sort of prospects there are since this model isn't even listed as "unsupported" on the website.<br>
<br>
Anyway, if anyone needs any info on it this was SANE gave me:<br>

Hello,<br>
<br>
I have just received a Canon LiDE 220 donated by Dany Qumsiyeh. Many thanks to him. Now I'm able to start working on this scanner.<br>
<br>
First tests show that this model operates like previous LiDE 2[01]0 models, on an undocumented (maybe gl127) ASIC.<br>
<br>
Since I now only have Windows 7 machines, I can't use usnsniff, and must adapt my decoding scripts to wireshark USB recording.<br>
<br>
I am going to build some sample tests programs based on log sniffing, without public datasheet this will be surely more complicated and longer than working with previous genesys ASIC. Once simple operations worked out, I'll turned it into a backend.<br>
<br>
This is going to take quite some time.<br>
<br>
Regards,<br>
Stef<br>
