Hi list, I've written a driver for Elan 0x0907 fp scanner. I don't know which model it is but it's marketed under various names for ex. Cobo C2 https://hardzone.es/app/uploads/2017/04/Cobo-C2-01.jpg. You can get it on AliExpress for about $25.
https://github.com/iafilatov/libfprint/commit/e19f7e339c65e5d001f3117b4a3308ee9234e492 It seems to work in general but there are some issues. First, it's technically a touch sensor but the images it produces are so small I never got more than 5 minutiae from them. So I'm using it as a swipe device instead. But it needs a steady swipe to produce a relatively decent image (I'm getting best results when staring the swipe from the finger tip). And I suspect that the motion compensation subroutines weren't built for this kind of use so the image has rough edges which could harden minutiae detection (dunno, it's my guess). I had to lower the threshold to 20. I'd really appreciate feedback about the driver. I wonder if it's worth trying to improve the image assembling logic to get more reliable verification. _______________________________________________ fprint mailing list fprint@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/fprint
