I wonder if it will really be interesting. Linux 2.4 produces no more proc_control: logs after starting iscan, but I have successfully done a preview and then a full scan in 400 dpi of an ISO-A4 sheet - this should amount to c. 46 MB data through USB 1.1. I'm gzipping the logs as they are 50 kByte each and gain >= 90%.
