IOCTL_BIOMETRIC_GET_INDICATOR & IOCTL_BIOMETRIC_SET_INDICATOR to turn the LED off.

IOCTL_BIOMETRIC_CAPTURE_DATA to monitor presence?

Apparently most fingerprint readers automatically turn off the LED indicator when HotFinger idles in identifying state for long enough (~3 minutes or so). After that, touching the fingerprint sensor toggles the LED on again. The fingerprint reader seems to be responsive even if the LED is turned off (fingerprints are correctly identified without noticeable extra delay).

Maybe this is good enough. Closing this issue for now, will reopen if necessary.
