Thanks for the answer. I will have a closer look at sanei_genesys_create_slope_tables to find out how to use it correctly. I did some more work for my Canon LiDE 35. Bulk access differs in all cases between gl646 and gl841. genesys_com.diff.gz moves the bulk functions into the chip specific source files. I also moved the last two occurences of send_slope_table in genesys.c to genesys_gl646.c and genesys_gl841.c, since the gl841 uses 5 tables instead of 2(and therefore should initialize them). I was able to get the scanner past most stages in scanning a page with scanimage, though i doubt it scans anything correctly. Sane now hangs while trying to read data from the scanner. It gets a block of data, but never request another one. I will investigate this one further. If anyone is interested, the changes are in genesys_gl841.diff.gz. genesys_gl841.diff.gz must be applied after genesys_com.diff.gz.
