8087:0024 is not a fingerprint scanner, it's rate matching hub

http://h20565.www2.hp.com/hpsc/swd/public/detail?swItemId=ob_106866_1&sp4ts.oid=5229488 This is the driver but is incompatible with arch

anarsoul commented 7 years ago

Sorry, I don't have this device, thus I can't fix the driver. Recompile libfprint with debug logs (pass --enable-debug-log to configure) and file a bug with logs at https://bugs.freedesktop.org/enter_bug.cgi?product=libfprint

i compiled with ./configure --prefix=/usr sysconfigdir=/etc --disable-static --enable-debug-log .... dmesg | tail return:

You have to recompile libfprint, not fprintd

Feb 12 13:04:28 Arch fprintd[11342]: fp:debug [find_supporting_driver] driver Validity supports USB device 138a:003d

You're running patched libfprint that includes a wrapper that uses a binary driver from Validity. I'd guess you're missing this binary driver:

Feb 12 13:04:28 Arch fprintd[11342]: fp:error [dev_activate] libvfsFprintWrapper.so: cannot open shared object file: No such file or directory

But anyway contact patch author. Neither mainline libfrint nor my repo has this patch and thus I'm not responsible for this code.

darkstaring commented 7 years ago

The driver should be http://h20565.www2.hp.com/hpsc/swd/public/detail?swItemId=ob_106866_1&sp4ts.oid=5229488 . I extract the rpm with rpmextract but i can't implement... who can I ask to?

anarsoul commented 7 years ago

Sorry, I have no idea where your patch came from. I've just checked archlinux libfprint package and it doesn't have this patch.
