Hi, I'm working with a EgisTec ES603 (1c7a:0603). I am using the current HEAD from anarsoul git repository.
When I try to enroll or identify (with async methods), sometimes it works, but most of the time I get a result of -22 (EINVAL) in the callback. I tried debugging it, and it seems the error comes in the sanitize_img function (imgdev.c line 93) from a check of the image height (line 106-111, error comes in 110). By enabling logging, I can see that during an enroll sequence, my callback function is called twice from one call. The first call is good, where I get an FP_ENROLL_PASS swipe and the function exits as it should. It then immediately gets called again, however this is the one that fails with error -22. I then enabled logging in the library, and it seems that it detects the finger twice or something, and then removes some empty lines that end up with a blank image. Here's some debug output to gaze upon: drv:debug [__ssm_call_handler] 0x7fbae0000910 entering state 13 drv:debug [__ssm_call_handler] 0x7fbae0000910 entering state 12 drv:debug [__ssm_call_handler] 0x7fbae0000910 entering state 13 fp:debug [fpi_imgdev_report_finger_status] finger on sensor drv:debug [fpi_ssm_mark_completed] 0x7fbae0000910 completed with status 0 drv:debug [__ssm_call_handler] 0x7fbae0000a10 entering state 0 etes603:debug [m_capture_state] Capturing a fingerprint... drv:debug [__ssm_call_handler] 0x7fbae0000a10 entering state 1 drv:debug [__ssm_call_handler] 0x7fbae0000a10 entering state 2 drv:debug [__ssm_call_handler] 0x7fbae0000a10 entering state 3 etes603:debug [m_capture_state] Capturing a 1st frame... drv:debug [__ssm_call_handler] 0x7fbae0000a10 entering state 4 drv:debug [__ssm_call_handler] 0x7fbae0000a10 entering state 5 etes603:debug [m_capture_state] Capturing a 2nd frame... drv:debug [__ssm_call_handler] 0x7fbae0000a10 entering state 4 drv:debug [__ssm_call_handler] 0x7fbae0000a10 entering state 5 etes603:debug [process_remove_fp_end] Removing 354 empty lines from image etes603:debug [process_remove_fp_end] Removing 0 empty lines from image fp:debug [fpi_img_new] length=163840 etes603:debug [m_capture_state] Sending the raw fingerprint image (0x640) fp:debug [fpi_imgdev_image_captured] fp:debug [fpi_img_detect_minutiae] minutiae scan completed in 0.057886 secs fp:debug [fpi_img_detect_minutiae] detected 97 minutiae fp:debug [print_data_new] driver=12 devtype=0000 fp:debug [print_data_new] driver=12 devtype=0000 fp:debug [fpi_imgdev_report_finger_status] finger removed fp:debug [fpi_imgdev_report_finger_status] reporting enroll result async:debug [fpi_drvcb_enroll_stage_completed] result 3 Enroll stage callback Enrolling 41EB2014-617A-4953-8283-0B9DD01653FB System output: Accepted, scan finger again...

Enroll stage callback Enrolling 41EB2014-617A-4953-8283-0B9DD01653FB System output: Accepted, scan finger again... (1/5) is the output from my callback function, and as you can see it gets called twice from a single scan: Enroll stage callback Enrolling 41EB2014-617A-4953-8283-0B9DD01653FB Enroll failed with error -22 System output: Enroll error! Now the code works fine with the integrated UPEK (147e:2016) in my laptop, so any clues here? Thanks in advance!
