Error using ACR122U210 #5

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I have the ACR122U210 reader, and nfc-list display correctly the information 
from my device. I've downloaded the latest drivers from the manufacturer, also 
I've tried using several libnfc and mfoc versions as well. The error is this:

mfoc: ERROR: 

No sector encrypted with the default key has been found, exiting..

I've read that this is a problem with my version of the ACR122U, but I don't 
have any other reader to test.

First, MFOC could only recover keys when card have a least one known key. Next, 
your device could be a problem. Feel free to contribute a patch if you find a 
way to fix it.
