Comment 74 for bug 1641290

I have 0903.

Successfully installed driver.
First time I ran $:examples/img_capture it was fine;
then $:examples/enroll was also going fine and even managed to enroll the fingerprint for several times, but then stopped for some reason.
After that I never managed even to launch first command, got such report:
