Created attachment 423966 [details] Patch to libfprint-0.1.0-pre2 Description of problem: UPEK Eikon II reader not supported in current version of libfprint. Additional info: Upek Eikon model TCRD4C4 (aka "Eikon II") fingerprint reader device not supported by upstream libfprint. This Eikon II device is the fingerprint reader now being installed by Lenovo on recent T-series Thinkpads, among several others. Jorge Suárez de Lis has written a patch (discussed in the libfprint mailing list). A copy of the patch is attached.
That will not work, unless you do not compile the upeksonly device driver: $ grep -r 0x2016 . | grep 0x147e ./drivers/upeksonly.c: { .vendor = 0x147e, .product = 0x2016 }, ./eikonII.patch:+ { .vendor = 0x147e, .product = 0x2016 }, As those use the same device ID. Bug 504399 has updated patches, and some discussion on how to handle both drivers. *** This bug has been marked as a duplicate of bug 504399 ***
