It maybe that smartcard guys care only for CCID, but wouldn't it be an
overkill to implement an emulation of that for the driver? It can be
done, of course, but I think it would be much more complicated than
the current one. Is it really necessary to put such complexity into
the kernel? In my opinion, this should be handled in user-space.
