ok, I will look at them.

it's possible. I noticed that sc7816 was trying to dynamically bind to
different function names. Even after changing the names to match my IFD
.so, things didn't seem to work. I knew pcsc-lite worked (formaticc) so
I chose to patch libsc7816.

In my patched sc7816 yes, but my hardware software combination doesn't
seem to care. The extra byte value in my case is 0xff and I'm not sure
that value would correspond to an le.

I have a few AMEX Blue cards. I've called them numerous times but I've
never received the reader so I cannot test my driver with them. AFAIK,
the AMEX readers are serial and the GPR400 is pcmcia. I bought it on
Ebay as part of the IBM SmartCard security kit.
I haven't explored the Blue yet. Have you?

haven't seen one.
