What version of OpenSC, and ubuntu opensc? There have been some changes in
0.10.3 and 0.10.4 dealing with max_send_size and max_recv_size, and
commenting out the lines in the opensc.conf. These allow each card driver
to reduce the sizes if its card can not support the defaults of 255 and 256.
Thus multiple cards could be used with the same copensc.conf.
The admin can still set the sizes in opensc.conf, but should not have to do it.
