Comment 61 for bug 1641290

@Igor I compiled and ran the tests for your latest driver and found that it would not correctly enroll my fingerprint on the Asus UX490UA which uses the ELAN 04f3:0903 device.

This is the output:

====================================================

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
