Since I am working from recorded USB logs, only the hardware modes used by driver will be known. So the final backend will not be as complete as the genesys backend. For instance scan below 300 dpi are always done at 300 dpi for LiDE 110 and 210, if the 220 does the same, it will be highly unlikely I can have lower resolutions work since we don't have the datasheet. The same goes for hardware lineart. At the end we can expect a backend that works correctly by mimicking what can be found in USB logs. That will at least take me a couple of months. We can expect to make the LiDE 120 work once the LiDE 220 works, if they are as close as the LiDE 110 and 210 were (differing only by the highest sensor resolution). Regards, Stef

Yep Sir Voltz,
I am following you for long in hope that some day my Canon LiDE 120 will work in Ubuntu and I am in github too following you. Wish you luck.
