Comment 32 for bug 1641290

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
elan:debug [init_complete]
fp:debug [fpi_imgdev_session_error] error -71
async:error [fpi_drvcb_enroll_stage_completed] BUG at async.c:161
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.
