I think this is the same problem as in bug #202 already solved in SVN.

Ok I looked in the code and found that Touchatag is not really supported yet.
I personnaly patched the acr122_usb.c file to support my touchatag.
But my patch breaks the compatibility with previously supported devices
Maybe something more pretty can be done...

The init_frame that I send in acr122_usb_init seems to fix the problem seen
