I also gave it a try with 04f3:0903 in ASUS UX490UA.
Unfortunately I obtain the same results as Isaac Emesowum (iemesowum).
Once compiled and installed I'm able to execute fprint_demo (as superuser) and when I try to enroll I get the following errors (I enabled debugging):
elan:debug [elan_cmd_cb] unexpected transfer length
drv:debug [fpi_ssm_mark_aborted] error -71 from state 0
drv:debug [fpi_ssm_mark_completed] 0x55fae265b840 completed with status -71

async:debug [fpi_drvcb_enroll_stage_completed] result -71
async:debug [fp_async_enroll_stop]
elan:debug [dev_deactivate]
I also executed enroll (in examples folder) with the same result.
I don't know anything about lsusb so I didn't manage to understand what was going on.
