When I scan image by function fp_dev_img_capture in example img_capture.c I can scan images without reopening device. But when I scan image to enroll with function fp_enroll_finger_img it scans image first time( with result FP_ENROLL_PASS ) and when I call it second time without reopening device my program hands on scanning. How is it possible that scanning works when I scan to capture but hangs when I scan to enroll? Piotr Jarosz </body> </html>
