Comment 90 for bug 1641290

Hi, I have an Dell Latitude 7370 with an Elan fingerprint reader and can't get it to work

jeroen@nice:~/libfprint$ lsusb | grep -i elan
Bus 001 Device 003: ID 04f3:2335 Elan Microelectronics Corp.

I tried your fork of libprintf, Igor, and noticed you don't support ID 04f3:2335.
I added it to elan.h but unfortunately no joy:

jeroen@nice:~/libfprint/builddir_dbg/examples$ sudo ./enroll
This program will enroll your right index finger, unconditionally overwriting any right-index print that was enrolled previously. If you want to continue, press enter, otherwise hit Ctrl+C
