Confirmed on UX390U.
This bug should actually be a feature request. There is currently no
support for elantech fingerprint scanners in libfprint. Someone needs to
write a driver for it. It's proprietary, so that might be tricky.
** Attachment added: "lsusb -v (manual grep for elan)"
I gave it a try with 04f3:0903:
"This program will enroll your right index finger, unconditionally
overwriting any right-index print that was enrolled previously. If you want
