After each line the is a USB like this: 0x8e Read 0x01 That is obviously USB's common acknowledge signal? After that there's a continuous loop that is obviously front button scan/= check? So the 0x92 ... 0x8b+0x8e=3D0x00 is the loop for the init and standby rou= tine? And until those "BlindWrite"s end, that's the init of the scanner? So as there are so much questionmarks (and names like those "BlindWrite" steps that are just my own wrong name for them I came up with), maybe I should leech a USB specification docs for more close info, or could someo= ne tell me what to do next (except for clearing up actual scanned image logs= )... So what to do next, as I haven't yet found what backend is the closest on= e to massage for a quick-fix testing? -- amth
