Hi,sorry for wasting your time again, but I completely have no idea what to do next.
I copied AES3500 and changed only DATA_BUFLEN. My AES3400 driver scans one image correctly, but hangs on second one.Length of last USB packet with image data is exactly equal my DATA_BUFLEN ( 0x208d ). This packet contains image and all registers sent by device( last register in this packet, i checked it in documentation ).
I do not close the device - driver doesn't send anything after scanning. When I perform next scan, library hangs after writing: sync:debug [fp_enroll_finger_img] aes3400 will handle enroll stage 1/4.I have no idea what my driver does wrong. Have anyone usblogs from working aes-like devices continously scanning?
