The quality of raw images doesn't change so maybe the driver does some stuff to improve them internally (or maybe it just simplified their code...) ---------- Forwarded message --------- From: Sebastien Bechet <sebastien.bec...@osinix.com> Date: Wed, Nov 8, 2017 at 6:15 PM Subject: Re: [fprint] USB ID 04f3:0903 "Elan Microelectronics Corp."

Yes of the original driver as explain here: https://lists.freedesktop.org/archives/fprint/2017-March/000875.html (I think it was 20160516-Elan driver) I have done four traces: 1. windows boot (000c*1, 0009*2, then 403f) 2. record a fingerprint Windows driver do multiple cmd 9, then, 403f, then again with this pattern (I have done one try, i think it can change, with record quality) : cmd9*1 then 403f cmd9*7 then .. cmd9*7 then .. ....*9 then .. .....8........ 7 7 7 7 7 7 7 1 1 5 7 6 6 6 1 4 7 3. test a fingerprint cmd9*17 then 403f then 000b 4. windows shutdown noop I never see 4023 or 4024 cmd. _______________________________________________ fprint mailing list fprint@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/fprint _______________________________________________ fprint mailing list fprint@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/fprint
