Hi, I am currently try to solve the problems with the X12USL. The colored stripes look somewhat similar on all devices so I think it is not a hardware problem. What I urgently need is a log of the data that is transferred via SCSI when scanning with the windows (or Mac?) driver. I managed this for my scanner by using a patched version of wine running the original windows drivers and Levente Novak managed this for his scanner too. I don't know what is possible on a Mac, but if you have an idea, please let me know! There seems to be a growing interest in sopport of the X12USL, so it will be worth the work.
