The version of the MuscleCard applet might be different than the one I
developed the OpenSC support for. Its quite possible that the newer
applet has the class bytes changed on it. The applet Dave sent should
work with the existing opensc patch...
Since it seems the class bytes are the issue... I have attached a patch
that will enable the autodetection of the class bytes that the
'default' card module implementation uses.
