The AES4000 driver performs badly as well. As you've commented, the 
likely problem is that only a tiny area of the finger is sampled.

I imagine the windows driver (where the sensor seems to perform OK) has 
a fingerprint processing engine heavily tuned to small amounts of data. 
It's probably quite insecure as a result.

Thanks for the contribution!
